V-CRATERIS - PHOTOMETRIC ELEMENTS

The analysis of the photometric B and V light curves of the semidetach ed eclipsing binary V Crt, using the Wilson-Devinney method, yielded p hotometric elements, including a photometric mass ratio of 0.40. Assum ing the mass of the primary component to be 1.70 M-circle dot (FO V), the absolute elements of V Crt are found to be m(c) = 0.68 M-circle do t, R-h= 1.77 R-circle dot, R-c = 1.34 R-circle dot, log L-h = 0.87 L-c ircle dot, log L-c = -0.06 L-circle dot, M-bol,M-h = 2.52, M-bol,M-c = 4.84, log g(h) = 4.17, and log g(c) = 4.02. Since the secondary has a lready filled its Roche lobe and the primary is filling about 86% of i ts Roche lobe, it is suggested that in V Crt a reverse mass transfer m ay start in a short time.
