A preliminary comparison of photometric (MWSC) and trigonometric (TGAS) distances of open cluster stars
Dana Kovaleva, Anatoly Piskunov, Nina Kharchenko +1
Our goal was to compare the open cluster photometric distance scale of the global survey of star clusters in the Milky Way (MWSC) with the distances derived from trigonometric para…
Open star clusters in the Milky Way - Comparison of photometric and trigonometric distance scales based on Gaia TGAS data
Dana A. Kovaleva, Anatoly E. Piskunov, Nina V. Kharchenko +5
The global survey of star clusters in the Milky Way (MWSC) is a comprehensive list of 3061 objects that provides, among other parameters, distances to clusters based on isochrone f…
On utmost multiplicity of hierarchical stellar systems
Y. M. Gebrehiwot, D. A. Kovaleva, A. Y. Kniazev +5
According to theoretical considerations, multiplicity of hierarchical stellar systems can reach, depending on masses and orbital parameters, several hundred, while observational da…
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…
