Astrophys. 327 145 1997 1997A&A...327..145R Photometry, UBVRI Polarization Stars, variable circumstellar matter polarization stars: individual (RR Tau) stars: pre-main sequence stars: variables: other The results of coordinated Crimea-Dodaira simultaneous multi-bands photometric and polarimetric observations of the classical Herbig Ae/Be star RR Tau which cover fully the observed interval of its brightness changes are presented. Within the observed interval of its light variations the linear polarization of RR Tau anti-correlates with its brightness changes.
