Scientific paper

The analysis of the photometric B and V light curves of the semidetached eclipsing binary V Crt, using the Wilson-Devinney method, yielded photometric elements, including a photometric mass ratio of 0.40. Assuming the mass of the primary component to be 1.70 M_solar (F0 V), the absolute elements of V Crt are found to be m_c=0.68 M_solar, R_h=1.77 R_solar, R_c=1.34 R_solar, log L_h=0.87 L_solar, log L_c=-0.06 L_solar, M_bol,h=2.52, M_bol,c=4.84, log g_h=4.17, and log g_c=4.02. Since the secondary has already filled its Roche lobe and the primary is filling about 86% of its Roche lobe, it is suggested that in V Crt a reverse mass transfer may start in a short time.
