Abstract

For the rst time heavy element nucleosynthesis in the magneto- hydrodynamical (MHD) explosions of core-collapse supernovae are investigated using a massive star of 13M in a main sequence stage. Contrary to the case of the spherical explosion, jet-like explosion due to the combined effects of the rotation and magnetic eld lowers the electron fraction signicantly inside the layers above the Fe-core. Then, the anisotropic shock waves pass through the oxygen rich layers. As a consequence, we nd that the nucleosynthesis of the r- and p-process proceeds appreciably compared to the models previously considered.
