Precise Analysis of Two Kepler Detached Eclipsing Binary Stars KIC 3327980 and KIC 10156064

Stars are one of the most important objects to understand how the galaxies are formed; shaped and evolved. Hence, the determination of the absolute parameters of stars plays a crucial role. The absolute parameters (e.g. mass and radii) of the detached eclipsing binary stars could be determined with well accuracy. These accurate parameters could be used for understanding of the evolutional status of single stars in detailed. In this study, we carried out light curve solutions of two well-detached binaries KIC 3327980 and KIC 10156064 which were observed by Kepler space telescope. As a result, mass and radii of primary and secondary components were derived as M-1 = 1.64M(circle dot), M-2 = 1.42M(circle dot), R-1 = 2.08R(circle dot), R-2 = 1.66R(circle dot) for KIC 3327980 and M-1 = 1.67M(circle dot), M-2 = 1.05M(circle dot); R-1 = 1.92R(circle dot); R-2 = 1.06R(circle dot) for KIC 10156064. Additionally, the evolutionary status of the components of the systems were discussed and compared with the evolutional status of the other detached eclipsing binaries.
