This study presented a new analysis for the TESS-observed W Ursae Majoris (W UMa)
binary star YY Coronea Borealis (YY CrB). The light curve was analyzed by the PHysics Of …

We present new photometric data and LAMOST spectra for the W UMa binaries UV Lyn,
V781 Tau, NSVS 4484038, and 2MASS J15471055+ 5302107. The orbital and starspot …

New photometric observations and their investigation of the W UMa-type binary, BI CVn, are
presented. The variations of the orbital period were analyzed based on 12 new determined …

By using all available times of light minimum, the orbital period changes of a W UMa
eclipsing binary YY CrB have been investigated. Two possible orbital period variations are …

We report four new times of minimum light and the improved ephemeris for the well known
contact binary AM Leo. The O‐C diagram, constructed with all reliable timings found in the …

In this study we present photometric and spectroscopic variation analysis and an orbital
period study of a low-mass interacting system OO Aql. Simultaneous solution of the light and …

New multi-color photometry of the solar-type contact binary OO Aql was obtained in 2012
and 2013, using the 60 cm telescope at Xinglong Station of the National Astronomical …

We present the results of the study of the contact binary system BO CVn. We have obtained
physical parameters of the components based on combined analysis of new, multi-color light …

Photoelectric BVR light curves of the recently discovered eclipsing binary were studied for
the first time to derive the physical parameters of the system. The light curves were obtained …

Bu tez çalışmasında, örten çift U Pegasi'nin Ankara Üniversitesi Gözlemevi'nde 1989-2005
yılları arasında gerçekleştirilen fotometrik gözlemlerinden elde edilen 7 ışık eğrisi ve yine bu …
