Evolution of close binary systems parameter distributions
Dugasa Belay Zeleke, Seblu Humne Negu, Oleg Yu. Malkov
In this paper, we investigate the orbital and stellar parameters of low- and intermediate-mass close binary systems. We use models, presented in the catalogue of (Han et al. 2000)…
Theoretical Mass-Luminosity Relations in Gaia G-Band
Oleg Malkov, Dana Kovaleva, Aleksandr Zhukov +1
We have analyzed the retrieval of the relation between mass and absolute Gaia G magnitude as obtained from theoretical models by \cite{2012MNRAS.427..127B} for the stars of differe…
Search for Ultraviolet Luminous Objects in GALEX data
Sergey Karpov, Oleg Malkov, Gang Zhao
Selection of extreme objects in the data from large-scale sky surveys is a powerful tool for the detection of new classes of astrophysical objects or rare stages of their evolution…
Binary Star Population with Common Proper Motion in Gaia DR2
S. A. Sapozhnikov, D. A. Kovaleva, O. Yu. Malkov +1
We describe a homogeneous catalog compilation of common proper motion stars based on Gaia DR2. A preliminary list of all pairs of stars within the radius of 100 pc around the Sun w…
Long-period eclipsing binaries: towards the true mass-luminosity relation. I. The test sample, observations and data analysis
Alexei Yu. Kniazev, Oleg Yu. Malkov, Ivan Yu. Katkov +1
The mass-luminosity relation is a fundamental law of astrophysics. We have suggested that the currently used mass-luminosity relation is not correct for the M/M_sun > 2.7 range of…
Verification of Photometric Parallaxes with Gaia DR2 Data
Oleg Malkov, Sergey Karpov, Dana Kovaleva +10
Results of comparison of Gaia DR2 parallaxes with data derived from a combined analysis of 2MASS (Two Micron All-Sky Survey), SDSS (Sloan Digital Sky Survey), GALEX (Galaxy Evoluti…
