TL;DR: In this paper, a new shell-model Hamiltonian was proposed for neutrino-induced reactions on $56{pf}$ and $Ni{Ni} and the Gamow-Teller strength was found to be more spread compared to previous calculations and result in a considerably large branching ratio for the proton knock-out channel.
Journal ArticleDOI
The Evolution toward Electron Capture Supernovae: The Flame Propagation and the Pre-bounce Electron-Neutrino Radiation
Journal ArticleDOI
Three Dimensional Magneto Hydrodynamical Simulations of Gravitational Collapse of a 15Msun Star
Takami Kuroda,Hideyuki Umeda +1 more
TL;DR: In this paper, two different, three dimensional magneto hydrodynamical codes were developed for the simulation of massive star collapse, one in the Newtonian limit (NMHD) and the other in the fully general relativistic code (GRMHD).
Journal ArticleDOI
Explosive nucleosynthesis of ultra-stripped Type Ic supernovae: application to light trans-iron elements
TL;DR: In this paper, the authors investigate the explosive nucleosynthesis during two dimensional neutrino-driven explosion of ultra-stripped Type Ic supernovae evolved from 1.45 and 1.5 M CO stars.
Journal ArticleDOI
Stellar Yields of Rotating First Stars. II. Pair Instability Supernovae and Comparison with Observations
TL;DR: In this paper, the authors investigated the PISN nucleosynthesis taking both rotating and non-rotating progenitors for the first time, and showed that the initial and CO core mass ranges for PISNe depend on the envelope structures.
