Precise physical and kinematical parameters of massive eclipsing binaries in the Small Magellanic Cloud
M. Kaya, Ö. Çakırlı, B. Hoyman +3
The formation of massive stars serves an important field of study, requiring research into whether these stars need to form together within clusters of low-mass stars or if they ar…
Solar-type eclipsing binary KIC 4832197: Physical properties and intrinsic variability of the components
Orkun Özdarcan, Hasan Ali Dal, Ezgi Yoldaş
Comprehensive analysis of optical spectroscopy and space photometry of the solar type eclipsing binary system KIC\,4832197 is presented. The system is composed of F7V + F9V compone…
KIC 7385478: An eclipsing binary with a γ Doradus component
Orkun Özdarcan, Hasan Ali Dal
We present spectroscopic and photometric analysis of the eclipsing binary KIC\,7385478. We find that the system is formed by F1V + K4III-IV components. Combining results from analy…
A comprehensive study of the open cluster NGC 6866
Z. F. Bostanci, T. Ak, T. Yontan +15
We present CCD photometry of the field of the open cluster NGC 6866. Structural parameters of the cluster are determined utilizing the stellar density profile of the stars…
V369 Gem: A New Ellipsoidal Variable System With High Level Chromospheric Activity
H. A. Dal, E. Sipahi, O. Özdarcan
In this study, we present BVR photometry of V369 Gem in 2006 - 2008. We combined our V data with the data taken from the literature. We analysed all the data together and calculate…
High-Level Magnetic Activity on a Low-Mass Close Binary: GSC 02038-0293
H. A. Dal, E. Sipahi, O. Özdarcan
Taking into account results obtained from light-curve analysis and out-of-eclipse analyses, we discuss the nature of GSC 02038-00293 and also its magnetic activity behaviour. We ob…
The Nature of the Light Variation of the Unique Binary DK CVn
H. A. Dal, E. Sipahi, O. Özdarcan
We present BVR observations of DK CVn from 2007 and 2008. We analysed the BVR light curves of the system and obtained the system's parameters. Using the `q-search' method, we measu…
