Abstract:
Supernovae are the cosmic fireworks that mark the death of stars, wherein heavy elements are
forged and dispersed, leading to the galactic enrichment of the Universe. In core-collapse supernovae,
the collapse of the inert iron core in massive stars paves the way for the catastrophic
explosion. This gives rise to a range of observational signatures due to the diverse nature of the
pre-explosion star and its environment. The decoding of the progenitor’s properties and its immediate
environment therefore calls for a comprehensive study of these events. The underlying quest
of most current studies in this field is to map each of these explosions to a progenitor system in
order to construct a complete picture of the theory of stellar evolution.
