Quality flags for GSP-Phot Gaia DR3 astrophysical parameters with machine learning: Effective temperatures case study
Aleksandra S. Avdeeva, Dana A. Kovaleva, Oleg Yu. Malkov +1
Gaia Data Release 3 (DR3) provides extensive information on the astrophysical properties of stars, such as effective temperature, surface gravity, metallicity, and luminosity, for…
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…
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)…
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…
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…
Improved orbits and parallaxes for eight visual binaries with unrealistic previous masses using the Hipparcos parallax
J. A. Docobo, V. S. Tamazian, O. Yu. Malkov +2
Improved orbits are presented for the visual binaries WDS 02366+1227, WDS 02434-6643, WDS 03244-1539, WDS 08507+1800, WDS 09128-6055, WDS 11532-1540, WDS 17375+2419, and WDS 22408-…
