AB  - Çift yıldızların zamana bağlı radyal hız eğrilerinin analizi, bileşenlerin fiziksel parametrelerinin doğrudan belirlenmesine olanak sağlar. En doğru yörünge modellemesi elde etmek amacıyla geliştirdiğimiz BRaVe programı, yörünge parametrelerini ve hatalarını yüksek duyarlılıkla elde etmektedir. BRaVe, kendi içerisinde Bayes istatistiğine dayanan bir optimizasyon rutini içerir. Bu rutin sayesinde ele alınan çift yıldız sisteminin temel yörünge parametreleri en hassas şekilde elde edilebilmesi hedeflenmektedir. BRaVe kodu için referans yıldız olarak Capella A yıldızı seçilmiştir. Polarbase veri arşivinden alınan yüksek çözünürlüklü tayflardan CCF yöntemi ile radyal hızlar hesaplanmış ve yörünge parametreleri BRaVe aracılığı ile çözülmüştür.  Bu çalışmada elde edilen sonuçlar, literatür ile kıyaslanarak paylaşılmıştır.

N2  - The analysis of the time-dependent radial velocity curves of double stars allows direct determination of the physical parameters of the components. The program BRaVe, which we developed to obtain the most accurate orbital modeling, obtains orbital parameters and errors with high precision. BRaVe includes an optimization routine based on Bayesian statistics. This routine aims to obtain the basic orbital parameters of the considered double star system in the most precise way. Capella A was chosen as the reference star for the BRaVe code. Radial velocities were calculated from high-resolution spectra from the Polarbase data archive using the Cross Corelation Function (CCF) method and the orbital parameters were solved using BRaVe. The results obtained in this study are presented and compared with the literature.
