Özet

The first BVR light curves of the eclipsing binary V821 Cas are used to derive the physical parameters of the system. The light curves were obtained during 2000 and 2001 observational seasons at Ege University Observatory (EUO). Period variation of the system was also investigated. For the first time apsidal motion elements of the system were obtained from the O-C curve analyses. Preliminary absolute parameters of the components were computed taking into account the results of light curves analysis. Observational and theoretical internal structure constants were estimated to be log over(k, ¯)2,obs = - 2.66 and log over(k, ¯)2,theo = - 2.42, respectively. © 2006 Elsevier B.V.
