Scientific paper

The optical orbital light curve of the X-ray binary LMC X-3 is analyzed using a model comprising ellipsoidal variations, X-ray heating of the companion star, and the effects of an accretion disk (as an additional source of optical emission, partial X-ray shielding of the companion, and possible mutual eclipses). Using observational constraints on the system (mass function, apparent visual magnitude and spectral type of the companion star), it is found that the observed amplitudes of the optical light curve constrain the mass M(x) of the compact star in LMC X-3 to be within the range (4.5-6.5) (d/50 kpc) solar masses. Within the framework of this model for the optical variations of LMC X-3, the compact star in this system is likely a black hole.
