Comparison of the Orbital Properties of the Milky Way Globular Clusters from the Data of the Gaia DR2 and EDR3 Catalogs

Publikováno v: Astronomy Reports. 65:737-754

We provide new values of the orbital parameters of 152 globular clusters, which are calculated using the new mean proper motions obtained from the Gaia EDR3 catalog data. The orbits were integrated 5 Gyr back in an axisymmetric three-component potent

Study of the Influence of an Evolving Galactic Potential on the Orbital Properties of 152 Globular Clusters with Data from the Gaia EDR3 Catalogue

Autor: A. T. Bajkova, A. A. Smirnov, V. V. Bobylev

Publikováno v: Astronomy Letters. 47:454-473

We have studied the influence of an evolving gravitational potential of the Milky Way Galaxy on the orbital motion of 152 globular clusters with proper motions from the Gaia EDR3 catalogue and mean distances from Baumgardt and Vasiliev (2021). To con

Estimation of Galactic Spiral Density Wave Parameters Based on the Velocities of OB2 stars from the Gaia EDR3 Catalogue

Autor: V. V. Bobylev, A. T. Bajkova

We have analyzed the kinematics of 9750 OB2 stars with proper motions and parallaxes selected by Xu et al. from the Gaia EDR3 catalogue. The relative parallax errors for these stars do not exceed 10\%. Based on the entire sample of stars, we have fou

Analysis of galaxy kinematics based on Cepheids from the Gaia DR2 Catalogue

Autor: A. T. Bajkova, V. V. Bobylev, Alexey S. Rastorguev, M. V. Zabolotskikh

Publikováno v: Monthly Notices of the Royal Astronomical Society. 502:4377-4391

To construct the rotation curve of the Galaxy, classical Cepheids with proper motions, parallaxes and line-of-sight velocities from the Gaia DR2 Catalog are used in large part. The working sample formed from literature data contains about 800 Cepheid

We have analyzed the kinematics of OB2 stars with proper motions and parallaxes selected by Xu et al. from the Gaia EDR3 catalog. The relative parallax errors for all the stars in this sample do not exceed 10\%. Based on a sample of 9750 stars, the g

Estimation of the Gould Belt Scale Height from T Tauri Type Stars in the Gaia DR2 Catalog

Autor: V. V. Bobylev, A. T. Bajkova

Publikováno v: Astrophysical Bulletin. 75:267-277

We analyze the spatial and kinematic properties of a large sample of young T Tauri type stars in a 500 pc radius solar neighborhood, closely related to the Gould belt. The following parameters of the exponential density distribution have been determi

Kinematics of the Galaxy from Young Open Star Clusters with Data from the Gaia EDR3 Catalogue

Autor: V. V. Bobylev, A. T. Bajkova

We have analyzed the kinematics of open star clusters (OSCs) with the proper motions and distances calculated by Hao et al. based on Gaia EDR3 data. The mean line-of-sight velocities are known for a number of clusters from this list. We show that the
