Anisotropic Models of Dark Halos
N. Ya. Sotnikova, S. A. Rodionov
An iterative approach is used to construct spherically symmetric equilibrium models with an anisotropic velocity distribution. The potentialities of the method have been tested on…
An Iterative Method for Constructing Equilibrium Phase Models of Stellar Systems
S. A. Rodionov, E. Athanassoula, N. Ya Sotnikova
We present a new method for constructing equilibrium phase models for stellar systems, which we call the iterative method. It relies on constrained, or guided evolution, so that th…
An Iterative Method for the Construction of Equilibrium N-Body Models for Stellar Disks
S. A. Rodionov, N. Ya. Sotnikova
One widely used technique for the construction of equilibrium models of stellar disks is based on the Jeans equations and the moments of velocity distribution functions derived usi…
Estimating the Dark Halo Mass from the Relative Thickness of Stellar Disks
N. Ya. Sotnikova, S. A. Rodionov
We analyze the relationship between the mass of a spherical component and the minimum possible thickness of stable stellar disks. This relationship for real galaxies allows the low…
Optimal Choice of the Softening Length and Time-Step in N-body Simulations
S. A. Rodionov, N. Ya. Sotnikova
A criterion for the choice of optimal softening length and time-step for -body simulations of a collisionless stellar system is analyzed. Plummer and Hernquist spheres…
Bending Instability of Stellar Disks: The Stabilizing Effect of a Compact Bulge
N. Ya. Sotnikova, S. A. Rodionov
The saturation conditions for bending modes in inhomogeneous thin stellar disks that follow from an analysis of the dispersion relation are compared with those derived from -bod…
