| Outline of Final Research Achievements |
Core-collapse supernovae play important roles in the galactic history. In particular, heavy elements synthesized in their explosions are the main source of the iron-group elements and rare isotopes. Explosive nucleosynthesis has been theoretically studied by means of very simple numerical supernova model since the first-principle supernova simulation is computationally expensive and limited in a short time scale. We have demonstrated multi-dimensional long-term simulations employing a new numerical scheme and a super computer system at NAOJ. We found that some p-rich isotopes such as Mo and Ru are synthesized in a different environment in the supernova. We also found that the abundance pattern of the elements show interesting agreement with the solar abundance.
