Magnetorotational Supernova Explosions: Jets and Mirror Symmetry Violation

Magnetorotational processes can significantly affect the dynamics of core-collapse supernovae, resulting to magnetically driven jet-like explosions. The magnetic field topology of progenitor stellar cores is believed to be quite complex and is not known precisely. Such complex structures may differ...

Description
Summary:Magnetorotational processes can significantly affect the dynamics of core-collapse supernovae, resulting to magnetically driven jet-like explosions. The magnetic field topology of progenitor stellar cores is believed to be quite complex and is not known precisely. Such complex structures may differ substantially from usual dipole or quadrupole field, which may cause to additional anisotropy of magnetorotational explosions. The latter is a result of mirror symmetry violation of the progenitor magnetic field. Here we report the results of two- dimensional MHD modelling of the collapse and further magnetorotational explosion of a rotating magnetized stellar core. We consider the models with different magnetic field configurations with and without mirror symmetry in the progenitor magnetic field respectively to the equatorial plane. In this work, we study the explosion asymmetry as well as the possibility of a protoneutron star kick formation during the explosion phase.
