AM Leo'nun Fotometrik Analizi

Abstract

UBV light curves of AM Leo which is a short period W UMa type contact binary were obtained at Ankara University Observatory in 2005 and analyzed. Preliminary solutions of physical parameters of the system were carried out by using Binary Maker and Nightfall lightcurve analysis programs. Two different solutions were determined by adjusting and by fixing the mass ratio (q = 2.51). The solutions describe that AM Leo system has a W sub-type overcontact configuration with an inclination of - 82° and a very small temperature differences of the components.
