Generation of an observable turbulence spectrum and solitary dipole vortices in rotating gravitating systems.
Abstract
A nonlinear equation is derived for the dynamics of the perturbations of a small but finiteamplitude gas system of inhomogeneous density rotating as a rigid body. In the particular case of shortwave perturbations this equation reduces to the CharneyObukhov or HasegawaMima equation. The weak turbulence spectrum of the equation leads to familiar relationships between the main parameters of the galactic gas population and, in particular, to the stellar mass spectrum discovered by Salpeter (1955). The stationary LarichevReznik solution of the equation is obtained in the form of a dipole solitary vortex (modon) with a circular separatrix. Possible manifestations of modons in double galaxies, double gaalxy nuclei, and double stars are examined.
