Özet

We present the results of our investigation of the geometrical and physical parameters of the binary system LX Leo. Based on CCD BV R-c light curves, and their analyses with the Wilson-Devinney code, new times of minima and light elements have been determined. According to our solution, the system is a high mass-ratio, totally eclipsing, W-type W UMa system. Combining our photometric solution with the empirical relation for W UMa type systems by Dimitrow & Kjurkchieva (2015), we derived the masses and radii of the components to be M-1 = 0.43M(circle dot), M-2 = 0.81M(circle dot), R-1 = 0.58R(circle dot) and R-2 = 0.77R(circle dot). In addition, the evolutionary condition of the system is discussed.
