Scientific paper

The detection of optical light variability of Sk-67 deg 105, one of the most massive binaries in the Large Magellanic Cloud (LMC), enables in combination with known spectroscopic data the determination of empirical masses and radii of the components using a light curve synthesis program. It is found that the system is nearly in contact and presumedly passes through Case A mass transfer at the moment. The derived pseudoeccentricity of the orbit may be explained by non-uniform brightness distribution within the system.
