Abstract

In this work, the light curves of NSVS2175434, V783 And, ASAS J020753+2034.1 and NR CAM W Uma type eclipsing binary star systems were obtained by using 0.5 meter ATA50 telescope in Atatürk University Astrophysics Research and Application Center (ATASAM). The orbital period variations of the systems were analyzed using the "timing" method. Only the O-C diagram of NR Cam was performed because the eclipse times of the other systems in the literature are not sufficient. When the O-C diagram of the NR Cam system is examined, no clear change has been observed for the time being. However, more observational data are needed to understand whether changes will occur in the future.

Özet

Bu çalışmada NSVS2175434, V783 And, ASAS J020753+2034.1 ve NR CAM W Uma tipi örten çift yıldız sistemlerinin Atatürk Üniversitesi Astrofizik Araştırma ve Uygulama Merkezi (ATASAM) bünyesindeki 0.5 metrelik ATA50 teleskobu ile elde edilen örtülme ışık eğrileri sunuldu. Sistemlerin yörünge dönem değişimleri “zamanlama” yöntemi kullanılarak incelendi. NR Cam dışındaki sistemlerin literatürdeki minimum zamanları yeterli olmadığı için sadece NR Cam’ın O-C diyagramı oluşturuldu. NR Cam sistemine ait O-C diyagramı incelendiğinde net bir değişime şu an için rastlanılmadı. Ancak ilerleyen zamanlarda değişimin olup olmayacağını daha net görebilmek için daha fazla gözlemsel veriye ihtiyaç vardır.
