| Research Abstract |
Magnetized supernovae have attracted attention since the beginning of this century. Although numerical works so far have yielded insights about the dynamics of magnetized supernovae, neither the evolution of weakly-magnetized core-collapse nor effects of turbulent resistivity have been well understood. We have started this research program to clarify these matters. Since a development of a numerical code delayed, we could not carry out computations for weakly-magnetized cores. For effects of turbulent resistivity, we have done two-dimensional resistive magnetohydrodynamic simulations. As a result of computations, we found that the turbulent resistivity decreases both explosion energy and aspect ratio of shock surface.
