LS Del örten değişen çift yıldızının fotometrik analizi
Özet
In this thesis, the analysis of O-C curve including all available minima times collected from literature with new 7 ones and the light curves obtained from new photometric observations at Ankara University Observatory in 2005, 2006 and 2007, were done. The results of period variation analysis attributed to the mass exchange/loss mechanism in the system. B and V light curves of LS Del were analysed by Wilson Devinney (2003) codes to determine physical parameters of the system. The results of light curve analysis indicate that there are two cool spots on more massive component.
