Scientific paper

The nonspherical models of eclipsing binaries proposed by Wilson et al. (1973) and Wood (1973) are applied to the analysis of four epoch mean lightcurves of AC Bootis, a W Ursae Majoris-a system with W-type lightcurves. According to gravity-brightening coefficients, the components of AC Bootis have convective envelopes. Wilson's model yields a small degree of overcontact (0.06) for the binary system; in addition, the hotter component appears to be the one with lower mass.
