The rapid photometrical variability of some Ae/Be star envelopes.
Abstract
The results of narrowband photometry of several Ae/Be stars of different types are presented. The observations were performed with the Crimean Astrophysical Observatory 70-cm AZT-8 telescope with a 5-channel photoelectric spectrometer. Variability with a characteristic time of several minutes to several days is found in the H-alpha and H-beta lines and in the region beyond the Balmer limit. Consideration is given to some mechanisms which can explain this variability.
