Title: | Explosion Mechanisms of Core-collapse Supernovae and their Multi-Messenger Probes |
Date (JST): | Thu, Nov 30, 2023, 13:30 - 15:00 |
Place: | Seminar Room A |
Abstract: |
Core-collapse supernovae (CCSNe) are the spectacular explosions that mark the death of massive stars with initial masses greater than ~8 solar masses. They are the birthplaces of neutron stars and black holes as well as the factories of heavy elements. Understanding the explosion mechanism of CCSNe has become the equivalent of a millennium problem of modern astrophysics. In this talk, I will give an overview of our current understanding of CCSNe mechanisms, which has been greatly enhanced through advanced computer simulations. Additionally, I will discuss how multi-messengers from CCSNe, such as gravitational waves and neutrinos, can help to the explosion mechanism. I will also present a few examples highlighting the insights we can gain from studying multi-messengers of CCSNe, including neutrino and nuclear physics. |
