Title: Cassiopeia A: Supernova Remnant for a Case Study of Core-Collapse Supernova Explosion   

Abstract:

The explosion of core-collapse supernova (SN) is one of the fundamental problems in astrophysics. There has been considerable progress in both observation and theory recently, but our understanding of the final evolution and the explosion process is still limited. A practical approach to the problem is to study young Galactic supernova remnants (SNRs) where we can observe the fine details of the imprints of the SN explosion. Cassiopeia A (Cas A), which is the youngest (~340 yr) confirmed core-collapse SNR in the Milky Way, is a unique SNR providing an opportunity to see the detailed spatial and kinematic distributions of SN ejecta material, thus enabling us to reconstruct the SN explosion scene. In this talk, I will review recent developments in the study of this Type IIb SNR Cas A and introduce our near-infrared studies.
