Visual binary stars with known orbits in Gaia EDR3
Dmitry Chulkov, Oleg Malkov
3350 objects from the Sixth catalog of orbits of visual binary stars (ORB6) are investigated to validate Gaia EDR3 parallaxes and provide mass estimates for the systems. We show th…
Pairing function of visual binary stars
Dmitry Chulkov
An all-sky sample of 1227 visual binaries based on Washington Double Star catalogue is constructed to infer the IMF, mass ratio, and projected distance distribution with a dedicate…
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…
Catalogues, parameters and distributions of orbital binaries
Oleg Malkov, Dmitry Chulkov
The most complete list of visual binary systems with known orbital elements is compiled. It is based on OARMAC and ORB6 data and contains 3139 orbits for 2278 pairs. A refined subs…
Hidden population of Algols
O. Yu. Malkov, D. A. Kovaleva, L. R. Yungelson +4
We present results of Monte Carlo simulation aiming at the estimate of the frequency of semi-detached Algol-type binaries among the stars observed as single ones. When account is m…
Visual binary stars: data to investigate formation of binaries
D. Kovaleva, O. Malkov, L. Yungelson +1
Statistics of orbital parameters of binary stars as well as statistics of their physical characteristics bear traces of star formation history. However, statistical investigations…
