| description | Eclipsing binary systems are significant objects for astrophysical studies since they offer more accurate fundamental stellar parameters (mass, radius). In particular, the determination of the astrophysical parameters of semi-detached binary stars is important in terms of examining the physical processes that occur as a result of interactions between components such as mass transfers and mass losses, since one of their components fills the Rochelobe. Therefore, in this study, the first binary modeling of KIC 9788457 is presented to estimated the fundamental stellar parameters of the system. The photometric data of the system were taken from Kepler that provides highquality data. When the light curve was checked it was found that the more luminous massive component has a significant light contribution into total. Therefore, using the spectral energy distribution and also color index (B-V) values effective temperature (Teff ) value was estimated for the primary component. Utilizing this Teff value, the binary modeling of the system was carried out. As a result, fundamental physical parameters of KIC9788457 were obtained. The radius (R) and mass (M) values of the components are M1=1.89 ± 0.05 Msun and R1= 2.03 ± 0.02 Rsun for the massive component and M2=0.81 ± 0.02 Msun and R2= 1.74 ± 0.03 Rsun for the less massive component, respectively. Additionally, the distance of the system was determined to be 1407 ± 85 pc. |
