Gravitational waves from very massive stars collapsing to a black hole
Haruki Uchida, Masaru Shibata, Koh Takahashi +1
We compute gravitational waves emitted by the collapse of a rotating very massive star (VMS) core leading directly to a black hole in axisymmetric numerical-relativity simulations.…
Black Hole Formation and Explosion from Rapidly Rotating Very Massive Stars
Haruki Uchida, Masaru Shibata, Koh Takahashi +1
We explore the formation process of a black hole (BH) through the pair-instability collapse of a rotating Population III very massive star in axisymmetric numerical relativity. As…
Stability of rigidly rotating supermassive stars against gravitational collapse
Masaru Shibata, Haruki Uchida, Yuichiro Sekiguchi
We revisit secular stability against quasi-radial collapse for rigidly rotating supermassive stars (SMSs) in general relativity. We suppose that the SMSs are in a nuclear-burning p…
