Research Abstract

I studied the nature of gamma-ray bursts and supernovae, the first stars, and the chemical evolution of the universe. I constructed a theoretical model reproducing the first observations of shock breakout and proposed a distant supernova survey with shock breakout with the optical telescope. Furthermore, I calculated nucleosynthesis in gamma-ray burst-supernovae with 2 components of energy injection, i. e., relativistic jets and non-relativistic jets, and presented a theoretical model reproducing abundance ratio of titanium to iron in the extremely metal-poor stars which was difficult to be explained with the previous models.
