Bu çalışmada, iki örten değen çift
yıldız HT Vir ve V1073 Cyg  sistemlerinin
yayınlanmış minimum zamanları kullanarak yörünge dönem değişimlerini inceledik.
Sistemlerin O-C analizleri sonucunda, HT Vir sisteminin döneminin arttığı, buna
karşın V1073 Cyg sisteminin döneminin azaldığı bulundu. Dönem değişim oranları
HT Vir ve V1073 Cyg için sırasıyla 1.33 s/yüzyıl ve -0.43 s/yüzyıl olarak
belirlenmiştir. Aynı zamanda her iki sistem için elde edilen O-C grafiklerinde
periyodik değişim de görülmektedir. Periyodik değişim, çiftin etrafında olası görülmeyen
üçüncü bir bileşenin ile açıklanmıştır.

Orbital Period Changes of Contact Binaries: HT Vir and V1073 Cyg

In this
study, we investigated changes in the orbital period of two eclipsing contact
binaries HT Vir and V1073 Cyg using all published times of minima. From the
analysis of O-C residuals, it was
found that HT Vir indicates orbital period increase, whereas the period of
V1073 Cyg is decreasing. The changing rates of their periods have been
determined to be 1.33 and -0.43 s/century for HT Vir and V1073 Cyg,
respectively. In the distribution of O-C
graph for HT Vir and V1073 Cyg, periodic variations also exist. Periodic
changes were explained as being the result of a hypothetical third companion
around the eclipsing pair.
