| Outline of Annual Research Achievements |
This past fiscal year was a fruitful one with 7 papers published in refereed journals and 4 published in non-refereed form. The main scientific results were diverse in nature, spanning from studies of speculated progenitors of a special variety of Type Ia supernovae, parameter survey of core-collapse supernova remnant models and their X-ray emission signatures, mapping the velocity field of Tycho's supernova remnant and predicting its environment using hydro models, a predictive study of X-ray emission from SN 1987A for observation by XRISM and so on. This was a good conclusion to the 5 years of research surrounding this Kakenhi project. The whole period turns out to be not only fruitful but also exciting that it has led to a few new research directions.
