| Outline of Final Research Achievements |
We developed a new numerical code to perform numerical simulation of core-collapse supernovae by 3D neutrino-radiation hydrodynamics. This code is constructed, for the first time in the world, using the Boltzmann equation in the full 6 dimensions. This novel code is an essential tool to study the mechanism of supernova explosions, which is the final fate of massive stars, via the neutrino heating mechanism. We enabled ones to describe neutrino creation, propagation and annihilation for the neutrino heating in 3D space without approximations previously used. We revealed the characteristics of neutrino transfer in 3D space and its influence on the explosions.
