Abstract

The light curves for three eclipsing binaries in the Magellanic Clouds have been obtained using CCD u V[J]I[C] photometry. One target in the LMC, MACHO*05:36:48.7-69:17:00, is an eccentric system, e = 0.20, with a period of 3.853534 +/- 0.000005 d. Initial solutions indicate a primary component in the range T [eff, 1] = 20,000-35,000 K and the secondary T [eff, 2] 1000-2000 K cooler than the primary, with inclinations ranging i = 84.2o - 86.0o. Two targets in the SMC, MOA J005018.4-723855 and MOA J005623.5-722123, have periods of 1.8399 +/- 0.0004 and 2.3199 +/- 0.0003 days respectively. Both have circular orbits with the former being a semi-detached system.
