It is difficult to observe the physical conditions inside the supernova or its progenitor star immediately before and after the supernova explosion, where the important physics of stellar evolution and supernova explosions are concentrated. Our research focuses on the X-ray study of “supernova remnants\u201d in order to extract the internal information at the moment of a star’s death. The uniqueness of supernova remnants is that it is possible to observe different elements synthesized inside stars and supernovae, and to infer the internal physical states (electron fraction, density structure, etc.) from the amount of elements. In this colloquium, based on our recent X-ray research, we would like to discuss what kind of information can be obtained from supernova remnant observations, and what we can expect from future research on supernovae and their progenitors.<\/p>\n","protected":false},"excerpt":{"rendered":"
