초 록
In this talk, I discuss origin of elements in the universe and the stellar evolution. First, I discuss a few scenarios beyond the standard Bigbang nucleosynthesis. For example, I discuss dynamical screening effects in the primordial plasma and the effects from Starobinsky gravity model. As for the neutrino process, I present the nucleosynthesis by the neutrino in the CCSN, which is a unique nucleosynthesis, with more interesting effects such as neutrino oscillation in matter, neutrino self-interactions, shock effects, magnetic field and neutrino-induced reactions.
