Studying Massive Star Evolution from Progenitor to Supernova Remnant using Long-term Hydrodynamical Simulations and Machine Learning

This year, our team has published in a diverse variety of areas concerning the various aspects of supernovae and supernova remnants, with a spotlight casted on the interaction-powered emission from different evolutionary stages. These efforts are inline with the theme of this KAKENHI project which is to understand the late-stage evolution of massive stars.Publication in refereed journals: 1) T. Matsuoka, S.-H. Lee, K.
