Disk-to-halo mass ratio evaluations based on the numerical models of collisionless disks
A. V. Zasov, A. V. Khoperskov, N. V. Tyurina
We propose that the lower bound of the stellar radial velocity dispersion c_r of an equilibrium stellar disk is determined by the gravitational stability condition. We compared the…

Bending instability in galaxies: the stellar disk thickness and the mass of spheroidal component
N. V. Tyurina, A. V. Khoperskov, D. V. Bizyaev
We present results of numerical N-body simulations of a galactic stellar disk embedded into a spherical dark halo. The non-linear dynamics of bending instabilities developing in th…
