Abstract

In this study, the effect of the rotation on the gravitational collapse is investigated by two-dimensional numerical simulation. Although most simulations for rotational collapse so far have been performed by employing the simplified equation of state for numerical simplicity, we employed more realistic equation of state by Shen et al. The initial angular momentum distribution is based on the recent calculation by Heger et al. The results obtained are quantitatively consistent with the previous work by Müller et al. In addition, we find it possible to realize the anisotropic neutrino radiation, which supports the scenario, in which explosion is induced by the anisotropic radiation from oblate core by rotation (Shimizu et al.).
