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…

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…

Periodic changes in the morphology of the Galactic resonance rings

A. M. Melnik, E. N. Podzolkova, A. K. Dambis

We study the periodic enhancement of either trailing or leading segments of the resonance elliptical rings in the dynamical model of the Galaxy which reproduces distributions of ob…

Influence of the Galactic bar on the kinematics of the disc stars with Gaia EDR3 data

A. M. Melnik, A. K. Dambis, E. N. Podzolkova +1

A model of the Galaxy with the outer ring R1R2 can explain the observed distribution of the radial, VR, and azimuthal, VT, velocity components along the Galactocentric distance, R,…
