A photometric study of an ew-Type binary system: GV Leo
A photometric study of a contact binary system, GV Leo is presented. New observationswere done using the BVR filter bands.We find that a revised orbital period is 0.26673171d and the orbital period of this system is decreasing at a rate of dP/dt = -4.95 × 10-7 d yr-1. The photometric solutions are f...
