Searching For Wide Binary Stars with Non-coeval Components in the Southern Sky
Alexei Kniazev, Oleg Malkov
We have completed our observational program to search for wide binary systems with non-coeval components in the southern sky and report our results here. The final set of four syst…
Wide binary stars with non-coeval components
Oleg Malkov, Alexei Kniazev
We have estimated masses of components of visual binaries from their spectral classification. We have selected pairs, where the less massive component looks more evolved. Spectral…
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…
Statistical relations between stellar spectral and luminosity classes and stellar effective temperature and surface gravity
O. Yu. Malkov, D. A. Kovaleva, S. G. Sichevsky +1
We have determined new statistical relations to estimate the fundamental atmospheric parameters of effective temperature and surface gravity, using MK spectral classification, and…
Variable binaries and variables in binaries in the Binary Star Database BDB
D. Kovaleva, O. Malkov, P. Kaygorodov
The BDB, Binary star DataBase http://bdb.inasan.ru combines data of the catalogues of binary and multiple stars of all observational types. There is a number of ways for variable s…
