Stellar models of Betelgeuse constrained using observed surface conditions
Tianyin Luo, Hideyuki Umeda, Takashi Yoshida +1
We study stellar models for Betelgeuse using the HR diagram and surface abundances as observational constraints. Previous studies on Betelgeuse have not systematically investigated…
A three-dimensional hydrodynamics simulation of oxygen-shell burning in the final evolution of a fast-rotating massive star
Takashi Yoshida, Tomoya Takiwaki, David R. Aguilera-Dena +5
We perform for the first time a 3D hydrodynamics simulation of the evolution of the last minutes pre-collapse of the oxygen shell of a fast-rotating massive star. This star has an…
Ultra-delayed neutrino-driven explosion of rotating massive-star collapse
Sho Fujibayashi, Koh Takahashi, Yuichiro Sekiguchi +1
Long-term neutrino-radiation hydrodynamics simulations in full general relativity are performed for the collapse of rotating massive stars that are evolved from He-stars with their…
Impact of binary interactions on the diffuse supernova neutrino background
Shunsaku Horiuchi, Tomoya Kinugawa, Tomoya Takiwaki +2
Binary interactions, especially mass transfer and mergers, can strongly influence the evolution of massive stars and change their final properties and the occurrence of supernovae.…
Three-dimensional Hydrodynamics Simulations of Precollapse Shell Burning in the Si- and O-rich Layers
Takashi Yoshida, Tomoya Takiwaki, Kei Kotake +3
We present 3D hydrodynamics simulations of shell burning in two progenitors with zero-age main-sequence masses of 22 and 27 for 65 and 200 s up to the onset of gr…
Pulsational pair-instability and the mass gap of Population III Black Holes: Effects of overshooting
Hideyuki Umeda, Takashi Yoshida, Chris Nagele +1
Since the discovery of GW190521, several proposals have been put forward to explain the formation of a black hole in the mass gap caused by (pulsational) pair-instability, $M = 65-…
