Emission-Line Stars in the Vilnius Photometric System

Various types of emission-line stars, observed in the Vilnius photometric system, are analyzed. They include Be-type stars, Herbig Ae/Be stars, T Tauri-type stars and K- and M-type dwarfs with active chromospheres. It is shown that all stars of these types, except for late-type dwarfs, in their active stages can be identified by their interstellar reddening-free parameters. For emission-line stars of B and A types interstellar reddening determination is also possible.
