The bound mass of Dehnen models with centrally peaked star formation efficiency
B. Shukirgaliyev, A. Otebay, M. Sobolenko +12
Understanding the formation of star clusters with low star-formation efficiency (SFE) is very important to know about the star-formation history. In N-body models of star cluster e…
Damped perturbations in stellar systems: Genuine modes and Landau-damped waves
Evgeny V. Polyachenko, Ilia G. Shukhman, Olga I. Borodina
This research was stimulated by the recent studies of damping solutions in dynamically stable spherical stellar systems. Using the simplest model of the homogeneous stellar medium,…
The Lynden-Bell bar formation mechanism in simple and realistic galactic models
E. V. Polyachenko, I. G. Shukhman
Using the canonical Hamilton-Jacobi approach we study the Lynden-Bell concept of bar formation based on the idea of orbital trapping parallel to the long or short axes of the oval…
Simulation of the loss-cone instability in spherical systems. II. Dominating Keplerian potential
E. V. Polyachenko, P. Berczik, A. Just +1
A new so-called `gravitational loss-cone instability' in stellar systems has recently been investigated theoretically in the framework of linear perturbation theory and proved to b…
Simulation of the loss-cone instability in spherical systems. I. Dominating harmonic potential
E. V. Polyachenko, P. Berczik, A. Just +1
A new so-called `gravitational loss-cone instability' in stellar systems has recently been investigated theoretically in the framework of linear perturbation theory and proved to b…
Effect of Inner Lindblad Resonance on Spiral Density Waves Propagation in Disc Galaxies: Reflection over Absorption
Evgeny V. Polyachenko, Ilia G. Shukhman
Interaction of spiral density waves with stars in the vicinity of the inner Lindblad resonance in galactic discs is investigated using the linear perturbation theory and the leadin…
