- Abstract
- The parameters of the axisymmetric model of the gravitational potential of the Galaxy have been refined. The basic curve of the Galaxy’s rotation in the distance interval R ∼ 0 – 190 kpc was constructed using the velocities of masers, classical Cepheids, Red Clump stars, Blue Horizontal Branch stars, halo stars, globular clusters, and dwarf satellite galaxies of the Milky Way. The rotation curve was selected in such a way that there would be no dominant burst of circular velocities in the central (R < 2 kpc) region of the Galaxy. As a result, two two-component models of the galactic potential were constructed, including contributions from the disk and halo of invisible matter, as well as a three-component model with a small-mass bulge added in advance. Such models can be useful in studying the long-term orbital evolution of stars, open and globular star clusters in the central (R < 4 kpc) region of the Galaxy. A self-consistency test of the constructed models was carried out by comparing their rotation curves with a set of model curves that were generated using the Illustris TNG50 software package.
