New spectra of R CrB LSS




Spectropolarimetry of RCrB


New spectra of the peculiar star R CrB at deep minimum light were obtained in 2001 by V.Klochkova, V.Panchuk and M.Yushkin with the echelle spectrometer PFES inside the prime focus of the telescope BTA in combination with an analyzer of linear polarization at the different position angles P2. Due to strong weakening of a photospheric spectrum of the star we can see three components of the spectrum: a continuum devoid of photospheric lines, a collection of sharp emission lines, and the broad emission lines of the NaI doublet. The sharp emission lines are considered to be chromospheric lines.

RCrB, P2=110
RCrB, P2=155
