Abstract

In this paper, the first photometric solutions of two southern eclipsing binaries (XY Ant and HD 295082) are presented. The ASAS V filter light curves of the two systems were analyzed with Wilson-Devinney code. The photometric mass ratio of XY Ant and HD 295082 were derived to be 0.941±0.019 and 1.033±0.068, respectively. Absolute parameters of the components of these two detached binaries were estimated and their evolutionary stages are also discussed

İKİ AYRIK ÇİFT YILDIZ XY ANT VE HD 295082’NİN İLK FOTOMETRİK ÇÖZÜMLERİ

Abstract

ASAS V bandı ışık eğrileri Wilson-Devinney kodu ile analiz edilmiştir. XY Ant ve HD 295082’nin fotometrik kütle oranları, sırasıyla, 0.941±0.019 ve 1.033±0.068 olarak belirlenmiştir. Bu iki ayrık çift sistemin bileşenlerinin mutlak parametreleri tahmin edilmiş ve aynı zamanda evrim durumları tartışılmıştır
