V502 Ophiuchi Çift Yıldız Sisteminin Işık Eğrisi ve Dönem Analizi

Year 2009, Volume: 12 Issue: 2, 151 - 163, 01.04.2009

Abstract

V502 Ophiuchi örten çift yıldız sisteminin 2005 yılında TÜBİTAK Ulusal Gözlemevi’nde, BVR bantlarında elde edilen ışık eğrileri, sistemin fiziksel parametrelerini belirlemek üzere, güncel tayfsal kütle oranı da dikkate alınarak PHOEBE analiz programı ile modellendi. Analiz sonucunda W-türü bir W UMa sistemi olan V502 Oph’nin ışık eğrileri, birinci bileşen üzerinde güneş benzeri soğuk bir lekenin varlığı altında başarılı bir şekilde modellendi ve sisteme ilişkin güncel fiziksel parametreler hesaplandı. Ayrıca, Ankara Üniversitesi Rasathanesi’nde 2009 yılı içinde sistemin ek ışıkölçüm gözlemleri yapılarak yeni minimum zamanları elde edildi. Bu minimum zamanları, literatürden toplanan tüm yayınlanmış minimum zamanları ile birleştirildi ve sistem için güncel bir dönem değişimi analizi gerçekleştirildi. Bu analiz sonucunda ise sistemin yörünge döneminin azalmakta olduğu tespit edildi ve bu azalmaya neden olabilecek mekanizma için bileşenler arası kütle aktarımı önerildi
