Long-term changes of the Be star OT Geminorum.
BOZIC H., RUZDJAK D. and SUDAR D.
Abstract (from CDS):
We investigate the character of light variability of the bright Be star OT Gem . Two phases of the long-term light changes were distinguished: (o) a quiet phase which is characterized by mild light changes; and (o) an active phase in which the sudden increases of brightness up to 0.4mag in V occur. During the active phases, a cyclic oscillation of brightness of a period between 70 and 80 days is present, with the most probable value being 71.89d. A positive correlation was found between the light and colour variations and the emission strength in both phases.
