Physical characteristics of the Galaxy defining the oscillation period of librating orbits near the OLR of the bar
A. M. Melnik, E. N. Podzolkova
We studied librating orbits of stars near the Outer Lindblad Resonance (OLR) of the bar using the angle-action variables of Hamiltonian dynamics. The librating orbits change the di…

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…
