Ah Virgins Sisteminin Dönem Analizi

Abstract

A period study of double star AH Vir has been performed with published minimum times and new minimum times which obtained at Ankara University Observatoy. In order to designate the charactristic of period variation, an 0-C graph formed. 0-C graph shows a period increase with cyclic variation. Under the assumption of conservation of the total angular momentum, the period increase can be atrtributed to mass transfer from less massive to the massive one. Cyclic variation can be attributed to light-time effect due to presence of third body in the system. The related physical parameters derived in this assumption.
