抄録

We compute the collapse of Population III massive stars (the first stars in the universe) with 300 - 13500 M. In this study, we solve the general relativistic hydrodynamics and the neutrino transfer equations simultaneously and we also solve the evolution of space time of the spherically symmetric model. As a result, it is shown that the neutrino transfer plays a crucial role in the dynamics of gravitational collapse and the emitted neutrino spectrum does not become harder for more massive stars. We also evaluate the flux of relic neutrino background from Pop III massive stars and discuss the possibility to III massive stars and discuss the possibility to study the Pop III star formation history.
