Abstract

The calculations of supernova explosion are made, using the one-dimensional nonstationary equations of magnetic hydrodynamics for the case of cylindrical symmetry. The energy source is supposed to be the rotational energy of the system (the neutron star in the centre and the surrounding envelope). The magnetic field plays the role of a mechanism of the transfer of rotational momentum. The calculations show that the envelope split up during the dynamical evolution of the system, the main part of the envelope joins the neutron star and becomes uniformly rotating with it, the outer part of the envelope (∼10% mass) expands with large velocity, carrying out a considerable part of rotational energy and rotational momentum.

These results correspond qualitatively with the observational picture of supernovae explosions.
