Model of Jet Generation in Space Plasma

A new analytical model for the generation of axially symmetric jets (directed jets) in a nondissipative, nonequilibrium stratified plasma has been created in the magnetohydrodynamics approximation.

Description
Summary:A new analytical model for the generation of axially symmetric jets (directed jets) in a nondissipative, nonequilibrium stratified plasma has been created in the magnetohydrodynamics approximation. The model is based on the assumption of Schwarzschild convective instability in plasma and on the condition that the magnetic field lines are frozen into matter. It is shown that jets with poloidal velocity and magnetic fields are generated in such a plasma. The dynamics of the velocity field and the magnetic field and the dynamics and structure of the arising toroidal electric current are studied.
