We present the results of our investigation of the geometrical parameters of the W UMa-type binary system VSX J045718.3+405643 (short name VSX J0457) based on new CCD B, V and Ic light curves.Our observations were carried out during six nights in November and December 2016 using the 0.25 m telescope of the Stazione Astronomica Betelgeuse in Magnago, Northern Italy.Six new times of minima and light elements have been determined and the observed light curves were analysed using the Wilson–Devinney code.The output model reveals that the system is a contact binary of A-Subtype of the W Ursae Majoris systems with a mass ratio of q ∼ 0.26 and a degree of contact factor f ∼ 32%.The primary component is hotter than the secondary by 95 K, this suggests us that the system is under thermal contact.The high orbital inclination (i = 82°.2) implies that VSX J0457 is a total eclipsing binary system and the photometric parameters here obtained are quite reliable.The absolute physical parameters of the two components in VSX J0457 are estimated.Based on these estimated parameters the evolutionary state of the system components is investigated and discussed.Combining our photometric solution with the 3-D correlation obtained for contact binaries by Gazeas (2009) we derive the masses and radii of the components of this eclipsing system as M1 = 1.44M⊙, M2 = 0.38M⊙, R1 = 1.55R⊙ and R2 = 0.87R⊙.The distance to VSX J0457 was calculated as 147 pc from this analysis, taking into account interstellar extinction.
