Abstract
We present and discuss the observations of 14 Ae and A type shell star s in the visual, the H alpha 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 th e systems lie one magnitude above the main sequence and that a large p ercentage belong to double and triple systems.
