Simultaneous spectroscopic and photoelectric observations of AB Aur in 1983 - 1984.
Abstract
Photoelectric results demonstrated that during the observational period of AB Aur the star did not show any noticeable fading of light. Light amplitude did not exceed 0.1 st. magnitude. In periods of light increase, emission lines of hydrogen, ionized iron, Ca, are strengthened as in ordinary Be stars. Changes in hydrogen lines' structure were observed taking place in days and even hours.
