Eclipsing binaries in the young Large Magellanic Cloud cluster NGC 1850.

TAYLOR S.F.

Abstract (from CDS):

I present light curves for two detached eclipsing binary stars in the region of the LMC cluster NGC 1850, which is possibly a young globular cluster still in formation. One, a likely O-type star, is a newly detected eclipsing binary in the region of the very young subcluster NGC 1850A. This binary is among a small number of highly massive O-type stars in binary systems found in LMC clusters. These two eclipsing binaries are the first to be discovered in the well-studied NGC 1850, and the O-type star is the first eclipsing binary found in NGC 1850A. Light curves for two Cepheid variables in the NGC 1850 region are also shown. The discovery of two eclipsing binaries in the young globular-like cluster NGC 1850 is discussed in terms of the importance of the binary fraction to globular cluster evolution.
