Spectropolarimetry of RCrB 4>
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.
