Outline of Final Research Achievements

It has been a topic of major undertaking to update neutrino opacities in neutrino-radiation hydrodynamics code for understanding the explosion mechanism of massive stars via the multi-messenger prediction from such explosive stellar phenomena. Through the fostering joint project, I have succeeded in updating the neutrino opacities in the supernova code including recoil and weak magnetism, in-medium and strangeness contribution to neutrino-nucleon scattering, and electron capture rate on nuclei based on state-of-the-art shell model Monte-Carlo calculations. By performing multi-D supernova simulations with these updated neutrino opacities, I have investigated how these updates affect the explodability of massive stars based on the analysis of neutrino-driven convection and standing-accretion-shock instability, the result of which has been published. Furthermore, detailed comparison of the supernova code with ones from other international supernova research groups has been also conducted.

Academic Significance and Societal Importance of the Research Achievements

これまで、超新星爆発メカニズムの研究・並びにマルチメッセンジャー研究において、それぞれの研究グループが独立的にコード開発を行い、得られた結果の詳細な相互比較が行われることが極めて稀であった。本国際共同研究の受け入れ先であるマックスプランク研究所, 更には他の超新星研究グループとも国際共同研究を行い、同じ初期条件を用いて、ショックの時間発展、ニュートリノ光度・平均エネルギーなど、爆発に影響にある物理量について比較検討を行い、良く一致する結果を得た。今回行った数値コードの比較は、今後の更なる多次元計算における比較へ向けた礎を与えるもので、学術的意義の高い成果である。
