A Mechanism for Generating Magnetic Field by Vortex Processes in Stellar Plasma

摘要

The difference in viscous properties of proton and electron gases in fully ionized hydrogen plasma is shown to result in a possibility of generation in this plasma of the magnetic field, even if initially there was no field. As an example, a simplified planar stationary model of a magnetohydrodynamic process of the eddy sink type is considered. It is demonstrated that the intensity of the generated magnetic field strongly depends on plasma temperature, so that the range T = 100000-500000 K corresponds to the range of maximum magnetic induction B = 50-2700 G. Such values are frequently observed in ordinary stars, in particular, in solar flares.
