On the variable spectrum of HD 45677 (FS Canis Majoris).

ISRAELIAN G. and MUSAEV F.

Abstract (from CDS):

We have studied high-resolution optical spectra of the peculiar B[e] star HD 45677 (FS CMa) observed during 3 nights in October 1995. The main results of our analysis can be summarized as follows: (1) The complex and variable profiles of Hβ indicate the presence of matter outflow. Three blue-shifted absorption components have been detected. (2) The inverse P Cygni red-shifted profiles have been observed in the MgII 4481Å line indicating the infall of cool gas onto the star. (3) These observations confirm our previous estimate (Israelian et al. 1996A&A...311..643I) for the projected rotational velocity of the order of 70km/s. (4) Accreting gas collides with the atmosphere and/or inner disk material producing the so-called filling in by emission effect and/or extended red wings of HeI 5876Å line.
