Özet

BVR light curves of the recently discovered eclipsing binary V351 Peg were studied to derive the preliminary physical parameters of the system. The light curves were obtained at the TUBITAK*-Turkish National Observatory (TUG) during three nights in August, 2003. The solutions were made using Djurasevics inverse problem method. V351 Peg is a system in an overcontact configuration (f(over) similar to 21%) with a relatively small temperature difference between the components Delta T approximate to 20 K. The results suggest a significant mass and energy transfer from the more massive primary onto the less massive secondary. The hot area on the less massive star, near the neck region, can be considered as a consequence of this mass and energy exchange between the components through the connecting neck of the common envelope.
