UW CMa: A Questionable Contact System
Abstract
Using BRITE and SMEI photometry in conjunction with concurrent spectroscopy we attempt a thorough analysis of the O supergiant binary UW CMa. We explore and confirm previously noted asymmetries in the light curve which we are unable to model effectively. We also find the presence of an unexplained frequency at twice that of the orbit. We then discuss the state of the binary and whether or not this system is truly in contact.
