Abstract

CCD uVJ I C photometry was obtained for three eclipsing binaries in the Magellanic Clouds and the preliminary analyses of their light curves has been made using a modified Wilson code. The LMC system, MACHO*05:36:48.7-69:17:00, is detached and eccentric, most likely comprising of two similar stars. The system has apsidal motion with a period of 100 ± 5 years. Initial results for two other systems in the SMC, MOA J005018.4–723855 and MOA J005623.5–722123, indicate circular orbits with the former semi-detached and the latter detached with two stars of very similar temperature.
