Collapse of rotating very massive stellar core to a black hole and a disk

Yuichiro Sekiguchi

Using recently developed new full GR code in which a realistic EOS, electron capture, and neutrino emission processes are implemented, we performed simulations of collapse of rotating very massive stellar core to a black hole and a disk. I will talk about my recent work about this. It is found that the outcome sensitively depends on the amount of rotation. I will discuss assocition with GRB central engine.
