Abstract

We carried out a spectroscopic survey of several ${\rm B}$ , ${\rm Be}$ , and shell stars in optical and near-infrared regions. Line profiles of the ${\rm H}\alpha$ line and of selected $\ion{Fe}{ii}$ and $\ion{O}{i}$ lines are presented.

Key words: line: profiles / stars: emission-line, Be / stars: circumstellar matter / stars: atmospheres
