A spectroscopic study of luminous peculiar B-type stars.
Abstract
We report new optical and IR spectroscopic data on 10 stars listed by Carlson & Henize (1979). Distances and reddening for most of the stars in our sample were estimated from the interstellar Na I line strength. P Cygni stars are more luminous and more massive than the others. They also have more intense Fe II optical emission. The data suggest that HD 326823 is highly evolved, having the surface abundances altered. This object is probably in a phase prior to the WR stage.
