Abstract:
We developed a three-dimensional numerical model to investigate nonstationary processes in
gravitating N-body systems with gas. We used efficient algorithms for solving the Vlasov and Poisson
equations that included the evolutionary processes under consideration, which ensures rapid convergence at high accuracy. We give examples ofthe numerical solution ofthe problem on the growth of physical instability in the model of a flat rotating disk with a gaseous component and its three-dimensional dynamics under various initial conditions including a nonzero velocity dispersion along the rotation axis.
