"Influence of neutrino reemission processes in magnetic field on dynamics of protostar envelope"


Urca-processes of a neutrino reemission in a protostar ( supernova ) envelope with a strong magnetic field are investigated. It is shown, that in the toroidal magnetic field these processes can develope a torque which quickly unwind an envelope. A general expression for a force density alonge the field is obtained. Numerical estimations are presented. A possible influence of the "neutrino unwinding" effect on a dynamics of the protostar(supernova) envelope is discussed.
