摘要：

We performed simulations of PopIII stellar core collase to a black hole surrounded by a massive accretion disk in the context of collapsar model in full general relativity. We found that the accretion flows around the black hole are characterized by the inner NDAF-like and outer CDAF-like components. Due to the presense of CDAF-like component, neutrino luminosities vary violently in time. Such time-variability may be associated with the observed time-variability of GRB light curves.
