Multicolour time series photometry of the variable star 1SWASP J234401.81-212229.1.

KOEN C.

Abstract (from CDS):

1SWASP J234401.81-212229.1 may be one of a handful of contact binaries comprising two M dwarfs. Modelling of the available observations is complicated by the fact that the radiation of the eclipsing system is dominated by a third star, a K dwarf. New photometry, presented in this paper, strengthens this interpretation of the data. The existence of such systems will have implications for the statistical distributions of masses in hierarchical multiple star systems.
