Stars: Early Type, Emission Line, Variables
Scientific paper
We present and discuss the observations of 14 Ae and A type shell stars in the visual, the Hα region and the near infrared. At least 57% of these stars are spectrum variables. The Paschen lines are formed in a region which has the characterics of giant stars. We find that the systems lie one magnitude above the main sequence and that a large percentage belong to double and triple systems.
