Boxy/peanut shaping of a mature galactic bar in action-angle space
Viktor D. Zozulia, Anton A. Smirnov, Natalia Ya. Sotnikova +1
We study vertical resonant trapping and resonant heating of orbits. These two processes both lead to the growth of a boxy/peanut-shaped bulge in a typical -body model. For the f…
Resonance coupling in spiral arms: Patterns for flat rotation curve
Alexander A. Marchuk
To address questions about the physical nature and origin of spiral arms in galaxies, it is necessary to measure their dynamical properties, such as the angular speed, , or th…
Cross-method analysis of co-rotation radii dataset for spiral galaxies
Valeria S. Kostiuk, Alexander A. Marchuk, Alexander S. Gusev
A co-rotation radius is a key characteristic of disc galaxies that is essential to determine the angular speed of the spiral structure , and therefore understand its nature.…
Two-component gravitational instability in spiral galaxies
A. A. Marchuk, N. Y. Sotnikova
We applied a criterion of gravitational instability, valid for two-component and infinitesimally thin discs, to observational data along the major axis for 7 spiral galaxies of ear…
