Abstract
1SWASP J234401.81-212229.1 may be one of a handful of contact binaries comprising two
Mdwarfs. 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.
