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…

Influence of the resonance ring gravity on the stellar velocity distribution near the OLR of the Galactic bar
A. M. Melnik, E. N. Podzolkova
We constructed the 2D model of the Galaxy which initially includes an analytical bar, bulge, disk and halo. The model disk forms the outer elliptical resonance rings R1 and R2 loca…

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…
