| Research Abstract |
By performing three-dimensional hydrodynamics simulations with spectral neutrino transport based on the isotropic diffusion source approximation (IDSA) scheme, we reported the first results on an 11.2 solar mass progenitor model that is trending towards explosion by the neutrino-driven core-collapse supernova mechanism. Studying gravitational-wave signals and nucleosynthetic yields from multi-dimensional supernova models, we obtained a number of new results that would significantly effect the conventional paradigm on the supernova mechanism, which include impacts of equations of state, nuclear burning, and magnetorotational instability.
