Spatial orientation and shape of the velocity ellipsoids of the Gaia DR3 giants and subgiants in the Galactic plane
A. M. Dmytrenko, P. N. Fedorov, V. S. Akhmetov +8
We present the results of determining the parameters characterizing the shape and orientation of residual velocity ellipsoids from the Gaia DR3 red giants and subgiants. We show th…
Determining the parameters of the spiral arms of the Galaxy from kinematic tracers based on Gaia DR3 data
S. I. Denyshchenko, P. N. Fedorov, V. S. Akhmetov +2
We present the results of determining the parameters of the spiral arms of the Galaxy using the stars Gaia DR3, whose absolute magnitude is < 4, and which allow tracing spira…
The vertex coordinates of the Galaxy's stellar systems according to the Gaia DR3 catalogue
A. M. Dmytrenko, P. N. Fedorov, V. S. Akhmetov +2
We present the results of determining the coordinates of the vertices of various stellar systems, the centroids of which are located in the Galactic plane. To do this, the position…
Mapping the kinematic parameters of the Galaxy from the Gaia EDR3 red giants and sub-giants
P. N. Fedorov, V. S. Akhmetov, A. B. Velichko +2
We present the results of a kinematic analysis of red giants and subgiants whose centroids are in the plane of our Galaxy. For this, the positions, parallaxes, proper motions, and…
Kinematics of the Milky Way from the Gaia EDR3 red giants and sub-giants
P. N. Fedorov, V. S. Akhmetov, A. B. Velichko +2
We present the results of the kinematic investigations carried out with the use of spatial velocities of red giants and sub-giants containing in the ~EDR3 catalogue. The twel…
Analysis of modern astrometric catalogues in the Gaia era
V. S. Akhmetov, P. N. Fedorov, V. S. Tsvetkova +1
We investigate of the systems of proper motions of stars in the ground-based catalogues HSOY, UCAC5, GPS1 and PMA derived by combining with the Gaia DR1 space data. Assuming the sy…
Testing stellar proper motions of the TGAS using data of the HSOY, UCAC5 and PMA catalogues
P. N. Fedorov, V. S. Akhmetov, A. B. Velichko
We present an investigation of stellar proper motions of the TGAS catalogue and ground-based HSOY, UCAC5 and PMA catalogues derived by combining with the Gaia DR1 space data. This…
The investigation of absolute proper motions of the XPM Catalogue
P. N. Fedorov, V. S. Akhmetov, V. V. Bobylev +1
The XPM-1.0 is the regular version of the XPM catalogue. In comparison with XPM the astrometric catalogue of about 280 millions stars covering entire sky from -90 to +90 degrees in…
Determining the Orientation Parameters of the ICRS/UCAC2 System Using the Kharkov Catalog of Absolute Stellar Proper Motions
V. V. Bobylev, P. N. Fedorov, A. T. Bajkova +1
The absolute proper motions of about 275 million stars from the Kharkov XPM catalog have been obtained by comparing their positions in the 2MASS and USNO--A2.0 catalogs with an epo…
