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…

The determination of mass of stellar disks of galaxies from the kinematic data
A. V. Zasov, A. V. Khoperskov, N. V. Tyurina
Different ways of the determination of masses of galactic disks, based on the kinematic data, are briefly discussed. The analysis of the rotation curves which reach maximum inside…

Nuclear kpc-sized disks of spiral galaxies
A. V. Zasov, A. V. Moiseev
A comlex structure of nuclear disks of normal spiral galaxies was illustrated on the example of five galaxies, observed at 6m telescope. A problem of gravitational stability of nuc…
