Light-curve analysis and orbital period change of the extreme mass-ratio overcontact binary AW CrB.
BROENS E.
Abstract (from CDS):
Eighty-four times of minimum light are reported, derived from observations available in public archives, the literature and the observations presented in this paper. The orbital period study shows a continuously increasing period, at a rate of dP/dt = 3.58x10-7dyr-1, suggesting a mass transfer from the secondary component to the primary one, implying a further decreasing mass-ratio.
