Abstract:

We present spectroscopic orbits of four eclipsing binaries in the Magellanic Clouds, namely, HV 2241 and HV 2543 in the Large Magellanic Cloud and HV 1620 and AzV 73 in the Small Magellanic Cloud. From our spectra and orbital analysis we find that the components of these systems are all early OB-type stars with masses ranging from 14 up to 34 solar masses. The physical parameters derived for the binary components are found to be comparable with their Galactic counterparts.
