Start of orbit librations and the bar growth timescale
Ekaterina N. Podzolkova, Anna M. Melnik
We study a dynamical model of the Galaxy with an analytical bar that reproduces the radial velocity profiles as a function of the Galactocentric distance obtained from th…

Hercules stream and the outer elliptical ring R1R2
A. M. Melnik, E. N. Podzolkova
We study the formation of the Hercules stream in the model Galactic disk which includes the outer resonance ring R1R2 located near the Outer Lindblad Resonance (OLR) of the bar. Th…

Humps on the profiles of the radial-velocity distribution and the age of the Galactic bar
Anna Melnik, Ekaterina Podzolkova
We studied the model of the Galaxy with a bar which reproduces well the distributions of the observed radial, VR, and azimuthal, VT, velocities derived from the Gaia DR3 data along…
