The hydrodynamic (HD) global modes of oscillations in thin gaseous disks of solitary flat galaxies are numerically investigated. The unstable HD modes are shown to be generated in the gaseous disk when the rotation curve has a velocity “kink” (ve

The results of studies of the over-reflection mechanism for the development of hydrodynamical instability in the accretion disks of close binary stars are presented. The driving of this instability is shown to result in the generation of regular, lar

We report the first experimental observation of wave over-reflection from supersonic flows and over-reflection instability of such flows in laboratory simulations on differentially rotating free-surface shallow water. Characteristics of the instabili

A scheme of model experiments on differentially rotating free-surface shallow water is proposed for discovering and studying the over-reflection instability. The scheme allows suppressing two stronger instabilities possible in the simulations, i.e.,

The existence of a spiral-vortex structure is revealed by a numerical simulation of the dynamics of an accretion disc in close binary stars. This structure is not related to the tidal influence of a companion star. It is a density wave containing a o

The existence of a spiral‐vortex structure is revealed by a numerical simulation of the dynamics of an accretion disk in close binary stars. This structure is a density wave containing a one‐armed spiral and an anticyclonic vortex with the center
