An influence of turbulence on radial motion in gaseous disks of galaxies.
Abstract
A hydrodynamical model of gas rotation in galaxy disks is considered. It is shown that stationary rotation of a hot gas has to be conditioned by strong turbulence and accretion of matter on the centre of the galaxy. Relationships of intensity of turbulence, velocities of ordered and turbulent radial motion and accretion rate upon sound velocity are found.
