Stars, variable Combined data Supernovae The GCVS is the only reference source on all known variable stars. This version contains all of the electronically-readable version as distributed by the Sternberg Astronomical Institute and Institute of Astronomy (Russian Acad.Sci.), Moscow. It includes the catalog of variable stars, updated and completed with the seven Name-Lists of Variables Stars Nos.67-73 (see IBVS No.2681,1985; No.3058,1987; No.3323,1989; No.3530,1990; No.3840,1993; No.4140,1995; No.4471,1997), a catalog of suspected variables, a cross-index of variable star names, a catalog of extragalactic variables, and a catalog of supernovae.

The present improved electronic version of the GCVS4 Volumes I-V, combined with Name-Lists of Variable Stars Nos.67-73, are also available from Sternberg Institute via anonymous ftp to ftp.sai.msu.su, /pub/groups/cluster/gcvs... and via http://www.sai.msu.su/groups/cluster/gcvs/ . The information at this site is regularly updated (corrections of detected mistakes, improvements of identifications and coordinates, etc.). gcvs.dat is the combined computer-readable version of the GCVS4 Vols. I-III (Kholopov et al. 1985-1988) and Name-Lists of Variable Stars Nos.67-73 (1985IBVS.2681....1K, 1987IBVS.3058....1K, 1989IBVS.3323....1K, 1990IBVS.3530....1K, 1993IBVS.3840....1K, 1995IBVS.4140....1K and 1997IBVS.4471....1K) published in the system introduced during the preparation of the 4th GCVS edition. The total number of designated variable stars has now reached 31918; of them, 3506 stars enter the Name-Lists Nos.67-73. Errors detected in the printed Volumes I-III and in the Name-Lists were corrected; the file includes also improved equatorial positions for some variable stars. crossid.dat contains all variables, including extragalactic variables, stars from the Name-Lists, and stars suspected of variability since the compilation of the NSV catalog, ordered by right ascension (B1950). The authors tried to provide as complete lists as possible for the stars identified with the catalogues HD, BD, CoD, CPD, BS, ADS and for the stars with preliminary HV (Harvard Variable) designations. As for the other catalogues, their task here was more difficult since they had to rely upon references to source catalogue names made by variable star researchers; the tables in the present volume reproduce the materials used in their work, and incompleteness seems to be unavoidable. Starting with Name-List No.71, the identifications became more reliable and complete thanks to special effort of the compilers. The final, fifth volume contains data for variables in external galaxies (including the Magellanic Clouds) and for extragalactic supernovae (see evs*.dat and sn*.dat). All variables in the present data set are arranged in the order of their names inside constellations. For Name-list stars, the information follows the format of the Name-Lists, that is, it includes only coordinates, the variability type, the range of brightness variations, and references. The file nsv.dat is a compilation of 14811 stars suspected of variability and not finally designated as variables prior to 1980. It is the successor to the "Catalogues of Stars Suspected of Variability" published in 1951 and 1965 (Kukarkin et al.). Data contained in the present catalog include positions, magnitudes, variability types, alternate designations, and references to the literature. The computer version of NSV contains principally the same data as in the printed catalog, but only the data table without the textual material (bibliography, remarks) is included. Necessary corrections were introduced, as of June, 1997, and coordinates were improved, compared to the printed version, for about half of the stars in the catalog. The Sternberg Institute has started preparation of an electronic release GCVS 4.2 which will contain improved light elements, classifications etc. along with sufficiently accurate positional information. The first approach to this project has resulted in improved equatorial positions (B1950, J2000) for variable stars in the constellations of Andromeda, Antlia and Apus including the stars from the GCVS proper plus the stars from the subsequent Name-lists, with a new standard of positional accuracy, to 1 second of arc (IAU Inform. Bull. Var. Stars, in preparation). These positions have been incorporated in the present data set.

Constell Constellation numeric code --- Number Star number within the constellation --- Component Component identification designations of components of double/multiple stars: A,B; 1,2,3 ... (tau 1). Usually only one component of the binary is variable, but there exist two cases (CE Cas A,B; EQ Peg A,B) when both components are variable and enter the catalogue as separate lines. --- GCVS Variable star designation traditional transliterations of greek letters are used. Lower- and upper-case latin letters must be distinguished (e.g. u Her and U Her). --- NoteFlag Notes in published catalog see the document by Kholopov et al. (1985-1988). --- RAh Hours RA, equinox 1950.0 the position is not listed when the variable is equivalent to another catalogued variable ("=" in column Exists, byte 142). h RAm Minutes RA, equinox 1950.0 min RAs Seconds RA, equinox 1950.0 s DE- Sign Dec, equinox 1950.0 --- DEd Degrees Dec, equinox 1950.0 deg DEm Minutes Dec, equinox 1950.0 arcmin DEs Seconds Dec, equinox 1950.0 arcsec u_DEs position accuracy flags the real coordinates accuracy uses the symbols: (:) means right ascensions accurate to one second of time and declinations accurate to one tenth of an arcminute; (*) means declinations accurate to one arcminute. (') means right ascensions accurate to one minute of time and declinations accurate to one arcminute. --- VarType Type of variability type of variability. The system of variable star classification corresponds to the GCVS4, with six additions (ZZO, AM, R, BE, LBV, BLBOO) introduced in the Name-Lists 67- 72 and in the GCVS vol.V (see file "vartype.txt"). --- l_magMax ">" if magMax is a faint limit "<" if magMax is a bright limit "(" if magMax is an amplitude --- magMax Magnitude at maximum brightness mag u_magMax Uncertainty flag (:) on magMax --- f_magMax ")" if magMax is an amplitude --- l_magMin "<" if magMin is a bright limit "(" if magMin is an amplitude --- magMin Minimum magnitude or amplitude mag u_magMin Uncertainty flag (:) on magMin --- n_magMin Alternative photometric system for magMin Code for alternative photometric system. Field is non-blank if magMin is a magnitude or amplitude given in a system other than that indicated by magCode. An asterisk in the corresponding position means the amplitude measured in white light. --- f_magMin ")" if magMin is an amplitude --- magCode The photometric system for magnitudes the photometric system in which magMin and magMax are reported (see also Note on n_magMax, n_magMin). The main codes are P (photographic magnitudes) and V (visual, photovisual, or Johnson's V). See also the documents by Kholopov et al. (1985-1988) or Warren (1989). Several stars from the 68th Name-List have in these positions "1." designating the 1.04 micrometer band of the system introduced by G.W.Lockwood. The designations u,v,b,y refer to the Stroemgren system. The symbols "I" and "R" mean magnitudes in Cousins' I system. "g" designates magnitudes in the system of Thuan and Gunn; "T" stands for broad-band Tycho magnitudes formed from B and V measurements; "r" are red magnitudes not tied to a particular system. --- Epoch Epoch for maximum light, Julian days Epochs are given for minimum light for all eclipsing and ellipsoidal variables, as well as for RV Tau and RS CVn types, and for maximum for all other types. This rule may occasionally be broken, but this is explained only in the remarks to the catalog, which are not available in machine-readable form at this time. The epochs are Julian dates. For novae (types N) and supernovae (types SN), the Epoch is completed by a year of outburst in the YearNova column. d q_Epoch Quality flag on Epoch the following codes are used (see also note on Epoch) : ":" epoch is uncertain. "+" epoch may be later than that reported; "-" epoch may be earlier than that reported. --- YearNova Year of outburst for nova --- l_Period Code for upper or lower limits the following codes are used: ">" or "<" if period is a lower or upper limit, respectively. "(": the period is the mean cycle time of a U Gem or recurrent nova (in this case, there is ")" in n_Period column) --- Period Period of the variable star d u_Period Uncertainty flag (:) on Period --- n_Period Uncertainty notes on Period the following codes are used: "*N" if the period may be a multiple of the quoted value; "/N" if the period may be a fraction of the quoted value; ")" - see the note on l_Period. --- M-m/D Rising time (M-m) or duration of eclipse (D) this column holds the rising time (M-m) of intrinsic variables, or the duration of the eclipse (D) for eclipsing binaries. These values help to define the shape of the light curve. The value is given in percentage of the period of the star. % u_M-m/D Uncertainty flag (:) on M-m/D --- n_M-m/D Note for eclipsing variable the "*" indicates that the duration of the light constancy phase at minimum light (d) for an eclipsing variable is equal to zero. --- SpType Spectral type --- Ref1 Reference to a study of the star "00001" - if the main characteristics of the star were determined by the authors themselves. "00002" - "09148" - Vol. I GCVS (see Kholopov et al., 1985-1988). "09149" - "09558" - Vol. II GCVS "09559" - "10200" - Vol. III GCVS "V 001" - "V 554" - Vol. V GCVS (see file evs_ref.dat) "67001" - "73381" - Name-Lists Nos.67-73 (see file nl_ref.dat) If no chart is available for the variable, but the star is contained in one of the Durchmusterung catalogs or the Hubble Space Telescope Guide Star Catalog, the corresponding abbreviation (BD, CPD, CoD, GSC) is given. --- Ref2 Reference to a chart or photograph --- Exists Cases of non-existence of the variable etc. the following codes are used in column Exists: "N" in byte 142 if the star does not exist. "=" in byte 142 appears in three cases. First, it is used if the variable is equivalent to another catalogued variable. In such case, after the "=" symbol, the alternative name of the variable follows, and all necessary information on the star is to be found under that alternative name. Second, it is used for all variables of the Name-Lists Nos.67-73, it is followed by the two-digit number of the Name-list and the four-digit number of the star in the Name-list, and the information for the star follows the format of the Name-lists (see above). Third, the "=" symbol may be followed by the star's name in the GCVS Vol. V (see the file evs_cat.dat). This means that the star enters also Vol. V, and the information of Vol. V makes it possible to improve the data of Vols. I-III. In this case, the symbol "*" in byte 153 means the presence of remarks in Vol. V; the symbol(s) "n" or "n:" in bytes 154-155 means that the star is nonmember (possible nonmember) of the galaxy in question. --- RA2000h Hours RA, equinox 2000.0 h RA2000m Minutes RA, equinox 2000.0 min RA2000s Seconds RA, equinox 2000.0 s DE2000- Sign Dec, equinox 2000.0 --- DE2000d Degrees Dec, equinox 2000.0 deg DE2000m Minutes Dec, equinox 2000.0 arcmin DE2000s Seconds Dec, equinox 2000.0 arcsec Cat Abbreviated name of catalog or list -------------------------------------------------------------------- ADS = R.G.Aitken, 'New General Catalouge of Double Stars', Carnegie Inst. of Washington Publ. no.417, vols.I, II, 1932 AN = Preliminary designations of variable stars introduced by the 'Astronomische Nachrichten' AS = P.W.

Note that NGC 1466 is a globular cluster (not a galaxy) between the LMC and the SMC; we presented it separately, because it is not clear to which galaxy to attribute its variable stars. --- VarNo Variable star number within the galaxy variable star No within the galaxy. Number of the variable star in the galaxy. If in the literature for the considered galaxy there exist several different variable star numbering systems, we have introduced new numbers in the order of increasing right ascension for the equinox 1950.0. But if the variable star numbering system for the galaxy is practically of general use, we have retained it - if necessary, with additional numbers ordered by increasing right ascension. --- Name Variable star designation Variable star Designation.

The classification systems corresponds to the GCVS vols. I-III (catalog <II/139>), with the addition of the new "BLBOO" type, called after the prototype star BL Boo = NGC 5466 V19 referring to the so-called "anomalous Cepheids", i.e. stars with periods characteristic of comparatively long-period RRAB variables, but considerably brighter by luminosity.

In the latter case, they are usually distinguishable from visual magnitudes by the number of digits after the decimal point (as a rule, V system magnitudes are based upon photoelectric or CCD photometry). Letters U, B, R, I, J, H, K, L, M, N, O, Q mean, as a rule, magnitudes expressed in corresponding systems of broad-band photometry. --- Epoch Epoch The epoch expressed as Julian Date. For eclipsing and ellipsoidal variables, RV Tau and RS CVn stars, the catalogue gives epochs of minimum light, and for the rest of variables, epoch of maximum light. For novae (types N) and supernovae (types SN), the Epoch is completed by a year of outburst (YearNova column). d u_Epoch Uncertainty flag on Epoch --- l_P '(' for U Gem For U Gem stars and recurrent novae, the P column gives (in brackets) the mean cycle value, if known. --- P Period d u_P Uncertainty flag (:) on P --- n_P ')' for U Gem --- M-m/D M-m or D Duration of light increase from minimum to maximum (M-m) for intrinsic variable stars or the eclipse duration (D) for Algol type variables are expressed in hundredths of the photometric period for the star in question. An asterisk (*) in n_M-m/D means, for an eclipsing variable, that the duration of the constant brightness phase in minimum (d) for this star is equal to zero. % u_M-m/D Uncertainty flag (:) on M-m/D --- n_M-m/D Note for eclipsing variable --- SpType Spectrum If there exist several spectral type determinations for a star, we preferred more recent ones, taking into account reliability of each determination. We converted symbols "d" (dwarfs) and "g" (giants) into luminosity classes V and III. If a nova showed spectral features typical of novae during or after the outburst, a symbol (NOVA) is given in this column. If the spectrum shows features characteristic of U Gem variables, this column contains the symbol (UG). Continuous spectrum is designated "cont", the symbol "e" means emission spectrum, lower case letters "ea", "eb" in this column stand for "e alpha", "e beta". For RR Lyrae stars, spectral types from hydrogen lines are given. A plus sign (+) between two spectral type values means that spectra of two components of a spectroscopic binary are observed. Two spectral type values separated with a minus sign (-) mean the range of spectral type variations in the process of brightness changes. --- evsRef1 Reference for study of the star, see file evs_ref.dat --- evsRef2 Reference for chart or photograph, see file evs_ref.dat --- Desig1 designation in paper Ref1 --- Desig2 designation in paper Ref2 --- VarName Designation in gcvs.dat or nsv.dat --- nonMem Non-member note Symbols "n" or "n:" for nonmembers (possible nonmembers) of the galaxy in question. For the stars that enter the GCVS vols.

"An" means an anonymous galaxy "Intergal" is for cases when the supernova cannot be reliably attributed to a particular galaxy and is considered intergalactic. --- RAh RA 1950 (hours) of Parent galaxy h RAm Right Ascension 1950 (minutes) min RAs Right Ascension 1950 (seconds) s DE- Declination 1950 (sign) --- DEd Declination Deg. 1950 of Parent galaxy deg DEm Declination 1950 (minutes) arcmin DEs Declination 1950 (seconds) arcsec u_DEs Accuracy flags The real coordinates accuracy is denoted by (") means right ascensions accurate to one second of time and declinations accurate to one arcsecond; (:) means declinations accurate to one tenth of an arcminute; (') means declinations accurate to one arcminute. --- MType Type of the parent galaxy --- BT Integrated magnitude of parent galaxy mag u_BT Uncertainty flag (:) on BT --- n_BT Band indicator, blank for photographic --- maxDate Date of the SN's maximum or of discovery The date of the SN's maximum or of discovery, or of an isolated observation at high brightness. If maxDate or f_magMax contains an asterisk (*), it means that the date and/or the magnitude refer not to the maximum (not covered with observations), but to the EPOCH OF DISCOVERY or to an isolated observation at high brightness. As a rule, information about maxima was not included if it was based on considerable extrapolation. --- magMax Magnitude at maximum (light) of SN mag u_magMax Uncertainty flag (:) on magMax --- n_magMax Band indicator, blank for photographic --- f_magMax '*' if maximum not observed --- dRA Distance of SN from galaxy nucleus In line 393, 1970K, the offset is 0.3E arcsec oRA Orientation of dRA --- dDE Distance of SN from galaxy nucleus In line 732, 1988T, the offset is 0.4N arcsec oDE Orientation of dDE --- RASN.h Right Ascension 1950 (hours) of SN h RASN.m Right Ascension 1950 (minutes) min RASN.s Right Ascension 1950 (seconds) s DESN.- Declination 1950 (sign) --- DESN.d Declination 1950 (degrees) of SN deg DESN.m Declination 1950 (minutes) arcmin DESN.s Declination 1950 (seconds) arcsec u_DESN.s accuracy flags on SN position --- SNType SN classification Limited to types I (I-A, I-B) and II (II-l, II-pl), with possible indications of peculiarities (pec). --- Discov Name of the SN discoverer In case of several discoverers, the name of the first author of the discovery is given followed by "+" symbol. As a rule, information on independent rediscoveries is not presented in the remarks, for the sake of brevity. The abbreviation "BASST" in this column means that the supernova was discovered by the Berkeley Automated Supernova Search Team. --- snRef1 Reference for study of the star See file sn_ref.dat --- snRef2 Reference for chart or photograph --- SN Supernova designation, repeated if more than 1 line --- n_SN Doubtful (?), or rejected (-) SN --- Text Text of remarks --- snRef Reference number, repeated if more than 1 line --- --- Period following Reference number --- Text Text of reference --- NLnum Name-List number --- Ref Reference number In the present version the authors attempted to give Latin transliterations of Russian-language names of astronomical periodicals and books. They did not try to unify the Latin spelling of names with Cyrillic (or other) original forms, but simply tried to reproduce the Latin transcriptions in the publications referred to. Of course this may lead to some confusion, hopefully minor. If a paper enters lists of references of several Name-Lists, it appears several times in the present version. --- Text Text of reference --- NSV NSV number --- NSVLetter NSV letter suffix The letter "A" is present for one star, NSV 10360A, which is a completely different object from NSV 10360. --- u_NSV Dubitancy flag if a star's variability seems doubtful or erroneous to the catalog compilers --- NoteFlag1 Notes in published catalog See the document by Kukarkin et al.(1982). There are several data fields that can contain asterisks. These signify that more complete information will be found in the remarks to the published catalog. The remarks are, unfortunately, not machine readable, but they do contain much supplemental information. There, one will find information covering situations like, e.g.: 1. The discoverer of the light variability is not the author of the paper cited in the variability reference, or is one of several authors of the paper cited. In these cases, discoverers' names are given in italics in original transcriptions of the remarks. 2. The most important additional information about a star, although the NSV compilers did not intend to present complete bibliographies for any catalogued stars. 3. Remarks for visual binaries (in parentheses following the number of a star in the corresponding catalog) giving visual magnitudes for the individual components A and B, angular separations, and position angles for faint components (or semimajor axis of a relative orbit and period of orbital motion). Data for other components are then given where applicable. (Combined magnitudes are generally reported in the machine-readable table.) --- RAh Hours RA, equinox 1950.0 The position is not listed when the variable is equivalent to a GCVS star (column VarName). h RAm Minutes RA, equinox 1950.0 min RAs Seconds RA, equinox 1950.0 s DE- Sign Dec, equinox 1950.0 --- DEd Degrees Dec, equinox 1950.0 deg DEm Minutes Dec, equinox 1950.0 arcmin DEs Seconds Dec, equinox 1950.0 arcsec u_DEs accuracy flags The actual accuracy of coordinates is indicated with the symbols: (:) means right ascensions accurate to one second of time and declinations accurate to one tenth of an arcminute; (*) means declinations accurate to one arcminute. --- VarType Type of variability type of variability. The system of variable star classification corresponds to the GCVS4 (see file "vartype.txt"). --- magMax Magnitude at maximum brightness Magnitudes are reported to hundredths if the observations are photoelectric, to tenths or whole magnitudes if they are not. If only an amplitude has been measured photoelectrically, then the maximum magnitude is generally given to tenths only and the minimum is reported to hundredths. mag u_magMax Uncertainty flag on magMax --- l_magMin "<" if magMin is a bright limit "(" if magMin is an amplitude; with "><" prefix, the amplitude in the table is a lower or upper limit. --- magMin Minimum magnitude or amplitude mag u_magMin a light amplitude is reported for the minimum and it is given in steps Uncertainty flag (:) on magMin --- f_magMin ")" if magMin is an amplitude --- magCode The photometric system for magnitudes The photometric system in which magMin and magMax are reported (see also Note on n_magMax, n_magMin). The main codes are P (photographic magnitudes) and V (visual, photovisual, or Johnson's V). --- Ref1 Reference to a study of the star see the document by Kukarkin et al.(1982) Usually a 6-digit number coding, as a rule, the reference to the announcement of the discovery of variability. The first two digits give the year (in the 20th century) when the announcement was published (blank for the 19th century). The next four digits give the number in the list of references contained in the published catalog, which is generally the first publication announcing the possible variability. The numbers are followed by a letter code in most cases (byte 57) with the following meanings: K: the cited paper contains a chart or photograph of the field with the suspected variable marked. D: the cited paper does not contain a chart, but the star is catalogued in one of the Durchmusterungen (DM) (BD,CD,CPD). --- Desig Designation in paper Ref1 The identification of the suspected variable in the paper referenced above. DM numbers are given without a prefix, the standard naming convention of "The Henry Draper Catalogue" being used (BD for zones +89 to -22; CD for -23 to -51; CP for -52 to -89). Some identifications are given by coordinate designations, a 6-digit number consisting of hours, minutes, and seconds (or tenths of a minute) of time and degrees of declination with sign included. An asterisk (*) signifies that a designation is given in the remarks to the published catalog. Stars are sometimes designated with numbers from the catalogs of Zinner (ZI, 1929) and Prager (PR, 1934, 1937) because the original discovery publications were not available to the NSV compilers. The catalogs of Zinner and Prager give detailed references to early observations of such stars. --- SpType Spectral type Temperature classes and subclasses only are given. Most luminosity classes are III to V, but if a star is a supergiant, more detailed classification information is given in the remarks to the published catalog. The following symbols are used: AF A-F AM Am AP Ap BE Be E emission spectrum EA e sub alpha EV variable emission in spectrum FG F-G KM K-M OF Of PD Pd T characteristics of T Tauri stars --- Ref2 Chart reference see the document by Kukarkin et al.(1982) The coding for the numbers is similar to that used in the variability references described above, except that there are no letter codes. These are references to papers containing identification charts if no charts are given in the papers cited for the variability references. --- VarName Designation in GCVS 1) The alternative name of the variable. All necessary information on the star is to be found under that alternative name, in the gcvs.dat file. 2) The star's name in the GCVS Vol. V (see the file v.zip, where the explanation of the designations is also given). In this case, the symbol "*" in column 89 means the presence of remarks in Vol. V. --- NoteFlag2 Notes in catalog GCVS Vol.V --- vartype.txtDescription of variability types N.N. Samus, O.V.

Authors' addresses: N.N. Samus [Moscow Inst. Astron.] O.V. Durlevich [Sternberg Astron. Inst., Moscow] <gcvs@sai.msu.su> UNKNOWN UNKNOWN This catalogue gathers the files previously numbered <II/139> (GCVS4, vols I-III), <II/172> (GCVS4, vol, IV), <II/205> (GCVS4, vol. V), <II/140> (New Suspected Variables), and <II/195> (Name-Lists). Catalogues <II/139> and <II/140> were first documented by Warren (1988, 1989); the documentation for the catalogues <II/172> and <II/205> was prepared by N.N. Samus and O.V. Durlevich (Moscow), with F. Ochsenbein (CDS). The first version of this Combined Catalogue (September 1997) was prepared by N. Roman (ADC) with the help of N.N. Samus and O.V. Durlevich (Moscow). The second version of this Combined Catalogue (August 1998), which incorporates the 73rd Name-List of Variable Stars and improved equatorial positions in Andromeda, Antlia and Apus, was prepared by N.N. Samus and O.V. Durlevich. Files were slightly reformatted at CDS (F. Ochsenbein) to have searchable epochs. The version 1.2 of the file "crossid.dat" was included on 22 May 1999. A further correction (QW Nor = NSV 7374 instead of NSV 7334) was applied on 16-Jun-1999 at CDS (message from N.N. Samus to F. Ochsenbein) II_214A.xml
