| Abstract: | We have carried out numerical simulations of hydrodynamical processes occurring in the disks of spiral galaxies. The initial
state of the disk is an equilibrium stellar-gaseous configuration. The spherical component is described by a standard analytical
model for the gravitational potential. The behavior of the modeled disk in the presence of an external perturbation is analyzed.
The results of numerical simulations of stellar-gaseous galactic disks aimed at studying the formation of polygonal structures
in spiral galaxies are presented. The possible influence of spur-like formations on the appearance of polygonal structure
is studied. |
