The Evolution towards Electron-capture Supernovae: the Flame Propagation and the Pre-bounce Electron-neutrino Radiation
K. Takahashi, K. Sumiyoshi, S. Yamada +2
A critical mass ONe core with a high ignition density is considered to end in gravitational collapse leading to neutron star formation. Being distinct from a Fe core collapse, the…
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…
On the minimum mass of neutron stars
Yudai Suwa, Takashi Yoshida, Masaru Shibata +2
We investigate remnant neutron star masses (in particular, the minimum allowed mass) by performing advanced stellar evolution calculations and neutrino-radiation hydrodynamics simu…
The Low Detection Rate of Pair Instability Supernovae and the Effect of the Core Carbon Fraction
Koh Takahashi
The pair instability supernova (PISN) is a common fate of very massive stars (VMSs). Current theory predicts the initial and the CO core mass ranges for PISNe of 140-260 $M_\…
Neutrino-nucleus reactions on O based on new shell-model Hamiltonians
Toshio Suzuki, Satoshi Chiba, Takashi Yoshida +2
Neutrino-induced reactions on O are investigated by shell-model calculaions with new shell-model Hamiltonians, which can describe well the structure of -shell and -$sd…
Stellar Yields of Rotating First Stars. II. Pair Instability Supernovae and Comparison with Observations
Koh Takahashi, Takashi Yoshida, Hideyuki Umeda
Recent theory predicts that a first star is born with a massive initial mass of 100 . Pair instability supernova (PISN) is a common fate for such a massive star.…
