Abstract

In binary systems, it can be difficult to model changes in light curves due to the different inherent properties of the two components. In stars with such light variations, the nature of the pulsating variation component may contain uncertainties. In this study, the light variations of KOI-7253 (KIC 9913481), whose type cannot be determined exactly in the literature, were examined using high resolution Kepler Satellite data and the nature of the pulsating component was interpreted. Moreover, the light curve of the system was analyzed, and the absolute parameters were calculated. Finally, the existence of orbital change in the system was investigated, and the current evolution status was discussed.

Özet

Çift sistemlerde, iki bileşenin sahip olduğu farklı bünyesel özellikler nedeniyle ışık eğrilerindeki değişimleri modellemek zor olabilir. Böylesi ışık değişimlerine sahip yıldızlarda zonklama değişimi gösteren bileşenin doğası belirsizlikler içerebilir. Bu çalışmada, literatürde tam olarak türü belirlenemeyen KOI-7253 (KIC 9913481) çift sisteminin yüksek çözünürlüklü Kepler Uydu verileri kullanılarak ışık değişimleri incelenmiş ve zonklama gösteren bileşenin doğası yorumlanmıştır. Ayrıca, sistemin ışık eğrisi çözümlenerek salt parametreleri hesaplanmıştır. Son olarak, sistemde yörünge değişiminin varlığı araştırılarak mevcut evrim durumu tartışılmıştır.
