Scientific paper

Two-dimensional stellar collapse is studied, beginning with a uniformly rotating white dwarf near the stability border up to the formation of an equilibrium differentially rotating neutron star. The calculations are performed using a two-dimensional Lagrangian method with a triangular space lattice. It is suggested that the amplification of the magnetic field in the differentially rotating neutron star due to twisting leads to a magnetorotational explosion of the supernova. This is caused by an increase in the magnetic pressure, shock wave formation, and the transformation of the rotational energy into the energy of the explosion.
