Outline of Final Research Achievements

We have obtained a broad spectrum of new insights on the natures of supernova progenitor stars and circumstellar environment, through studying supernovae both through theoretical and observational methods. The work has led to a large step forward to understand unresolved problems in stellar evolution, especially in the final centuries of their lives. The work has utilized various different approaches, highlighted by "stellar and binary evolution", "supernovae and transient phenomena", "their environments". The issues have been tackled through theoretical simulations, multi-frequency observations from the ground and space, leading to many outstanding results (resulting in about 50 papers in refereed international journals). The synergy between different approaches is especially a highlight in this work.
