Abstract

In this study, which is based on spectral disentangling in binary systems, ε Lupi (HD 136504) has been studied. ε Lupi is a double-lined spectroscopic binary system (SB2) consisting of two early type B stars. A total of 575 spectra of ε Lupi downloaded from the PolarBase database were used for spectral disentangling. Before spectral disentangling, we cleaned telluric lines, merged orders, normalized the continuum of spectra. To obtain individual spectra of the components, FDBinary code was used. Consequently, the spectra of the components of the ε Lupi system were separated in the wavelength range 3920 - 8560 Å. The radial velocities and atmospheric parameters of the primary and secondary components will be found using with the resultant normalized spectra of ε Lupi.

Özet

Çift yıldız sistemlerinde tayfsal çözümleme konusunu ele alan bu çalışmada, ε Lupi (HD 136504) yıldızı incelendi. ε Lupi iki erken tür B yıldızından oluşan çift çizgili tayfsal çift (SB2) sistemdir. Tayfsal çözümleme için ε Lupi’ye ait PolarBase arşivinden indirilen toplam 575 tayf kullanıldı. Çift sisteme ait bileşen tayfları ayırmadan önce tellürik çizgileri temizleme, tayf parçalarını(order) birleştirme, süreklilik normalizasyonu vb. işlemler uygulandı. ε Lupi’ye ait bileşen tayfların ayrı ayrı elde edilmesi için FDBinary kodu kullanıldı. Sonuç olarak, ε Lupi’nin bileşen tayfları 3920 - 8560 Å dalgaboyu aralığında ayrıldı. Bu çalışma sonucunda ε Lupi’nin bileşenlerine ait normalize tayflar kullanılarak dikine hızlar ve atmosferik parametreler bulunabilir.
