Özet
Contact binary stars have an important role to understand how the binary stars evolve to a single star and explain to the physical processes of star merges. Hence, understanding of different type of contact binaries is valuable to explore sonic physical processes such as angular momentum loses, mass and heat transfers between components. In this study, we present the photometric analysis of two Kepler binary stars KIC 3221207 and KIC 6677225. As a result, it was found that both eclipsing binaries have large amount of common envelopes. The till-out factors of stars were determined to be 79 and 89 percent for KIC 3221207 and KIC 6677225, respectively. Furthermore, both systems show parabolic orbital period variations, while the third light contribution was found for KIC 3221207. In the result, we compare the target systems with similar, well-known contact binaries.
