Abstract

We compute the collapse of Population III (Pop III) massive stars with 300 - 13500 M for 18 models. In this study, we solve the general relativistic hydrodynamics and the neutrino transfer equations simultaneously to follow the evolution of space time under spherical symmetry. As a result, it is shown that the neutrino transfer plays a crucial role in the dynamics of the gravitational collapse and the emitted neutrino spectrum does not become harder for more massive stars. We also evaluate the flux of the relic neutrino background from Pop III massive stars and discuss the possibility to study the Pop III star formation history.
