Descripción
{ 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 4481 Angstroms line indicating the infall of cool gas onto the
star. (3) These observations confirm our previous estimate (Israelian et
al. 1996) for the projected rotational velocity of the order of 70 km
s(-1) . (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 5876 Angstroms line.}
