Abstract

Bu çalışmada,
Kepler uzay teleskobu tarafından gözlenen basık yörüngeli ayrık tür KIC 7821010
çift yıldız sisteminin ışık eğrisi ve ETV eğrisi analizleri yapılmıştır. Işık
eğrisi ve bileşenlerin dikine hız eğrileri eş zamanlı olarak analiz edilmiş ve
elde edilen çözümler kullanılarak sistemin mutlak parametreleri hesaplanmıştır.
ETV analizi için Python tabanlı iki adet kod yazılmıştır. Bu kodlar
kullanılarak Kepler veritabanından alınan ışık eğrilerinden tutulma zamanları
hesaplanmış ve ışık zaman etkisi ile birlikte dinamik etki de gözönüne alınarak
ETV analizi yapılmıştır. ETV grafiğinde değişime neden olarak sisteme çekimsel
olarak bağlı yaklaşık 991± 2 gün dönemli ve 2.05 ± 0.06 Mj kütleli
üçüncü bir bileşenin varlığı önerilmiştir.
