Orbital Period Changes in IO Cep, IM Cep and TX Ari: Path to Masses of Distant Components

V. Bakış, Z. Eker, H. Bakış +7

Three Algol-type binary systems (IO Cep, IM Cep and TX Ari) showing cyclic orbital period changes are studied. The combination of time of minimum data from the ground-based observa…

Influence of the Galactic bar on the kinematics of the disc stars with Gaia EDR3 data

A. M. Melnik, A. K. Dambis, E. N. Podzolkova +1

A model of the Galaxy with the outer ring R1R2 can explain the observed distribution of the radial, VR, and azimuthal, VT, velocity components along the Galactocentric distance, R,…

Contribution of binary stars to the velocity dispersion inside OB associations with Gaia DR2 data

A. M. Melnik, A. K. Dambis

We estimated the contribution of binary systems to the velocity dispersion inside OB-associations derived from Gaia DR2 proper motions. The maximum contribution to the velocity dis…

Distance scale for high-luminosity stars in OB associations and in field with Gaia DR2. Spurious systematic motions

A. M. Melnik, A. K. Dambis

We calculated the median parallaxes for 47 OB associations including at least 10 stars with known Gaia DR2 parallaxes. A comparison between trigonometric and photometric parallaxes…

Galactic resonance rings. Modelling of motions in the wide solar neighborhood

Anna M. Melnik

Models of the Galaxy with analytical Ferrers bars can reproduce the residual velocities of OB-associations in the Sagittarius, Perseus and Local System stellar-gas complexes locate…

Kinematics of OB-associations and the new reduction of the Hipparcos data

A. M. Melnik, A. K. Dambis

The proper motions of OB-associations computed using the old (Hipparcos 1997} and new (van Leeuwen 2007) reductions of the Hipparcos data are in a good agreement with each other. T…
