Title: Photometery of Nine Eclipsing Binaries in the Field of NGC 2362
Abstract: W Ursa Majoris stars (EWs) are contact binaries with unique light curves. They have been observed to exhibit changes in orbital period, which has been attributed to mass transfer within the system. EWs are also known to obey a relationship between their period, color, and absolute brightness, which has been calibrated and can be used as a distance indicator. We discovered nine eclipsing systems in the field of NGC 2362 by analyzing photometric $I$-band data obtained in 2006 January with the 0.8-m telescope at McDonald Observatory in Fort Davis, TX. Some of these eclipsing systems have light curves representative of EWs. We intend to verify whether or not these systems can be considered members of the young cluster NGC 2362 using the Period-Luminosity-Color (PLC) relationship. If these stars are truly members of the young cluster NGC 2362, they will provide direct measurements of the stellar mass, and a ratio of effective temperatures for stars within a cluster that has an age estimated to be between 5 and 13 Myr.
