Optical Observations of Gamma-Ray Bursts, the Discovery of Supernovae 2005bv, 2005ee, and 2006ak, and Searches for Transients Using the "MASTER" Robotic Telescope
V. M. Lipunov, V. G. Kornilov, A. V. Krylov +11
We present the results of observations obtained using the MASTER robotic telescope in 2005 - 2006, including the earliest observations of the optical emission of the gamma-ray burs…
MASTER: The Mobile Astronomical System of Telescope-Robots
V. M. Lipunov, A. V. Krylov, V. G. Kornilov +9
We present the first russian robot-telescope designed to make prompt observations of gamma-ray bursts (http://observ.pereplet.ru). The telescopes are near Moscow. The system of tel…
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…
Minimum Velocity Dispersion in Stable Stellar Disks. Numerical Simulations
A. V. Khoperskov, A. V. Zasov, N. V. Tyurina
N-body dynamical simulations are used to analyze the conditions for the gravitational stability of a three-dimensional stellar disk in the gravitational field of two rigid spherica…
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…
