Outline of Final Research Achievements

We tried to solve one of the largest problem in recent studies of core-collapse supernovae. In 3D neutrino radiation hydrodynamic simulations, the obtained explosion energies and mass of ejected Ni is significantly smaller than those in the observations.
We updated the cross section of neutrino and nucleons, that was proposed by Horowitz 2017. We found that this change strongly affects the dynamics of the shock in the supernovae.

Academic Significance and Societal Importance of the Research Achievements

超新星爆発は恒星の最期の大爆発であり、その爆発メカニズムの解明は天文学者の悲願である。核物理のアップデートにより、このメカニズムの理解が一歩進み、より現実的な計算ができるようになった。メカニズムはまだ完全に解明されたわけではないが、このアップデートなくしては正解には至れない。超新星爆発の研究において非常に重要な一歩となったと考えられる。
