INFLUENC E O F TH E CHEMICA L COMPOSITIO N ON THE CONVECTION, MERIDIONAL CIRCULATION AND DIFFERENTIAL STELLAR ROTATION

A. Z. Dolginov, A. V. Klyachkin Ioffe Physical-Technical Institute,194021,Leningrad,Politekhnicheskaya,26,USSR

Analitical solutions for the distribution of the temperature , velocities and helium mass concentration in the rotating helium-hydrogen star are obtained. The linear and nonlinear regimes of the convection are considered. The threshold and the character of the convection are investigated. The numerical estimations are obtained.
