Comparing explodability predictions from a parameter-optimized semi-analytic model with structure-based progenitor criteria
Yuxin U. Wu, Hideyuki Umeda, Koh Takahashi
Three-dimensional (3D) simulations of neutrino-driven core-collapse supernovae are among the most reliable tools for predicting explosion outcome. However, their high computational…

Physical Conditions for Synthesis of Sc, Ti, and V in Neutrino-driven Supernovae
Ryota Hatami, Nozomu Tominaga, Takashi Yoshida +2
We present the results of simulations of nucleosynthesis in a core-collapse supernova (CCSN) including the neutrino process. Using the Si layer of zero-metal progenitor…

Inhomogeneous stellar mixing in the final hours before the Cassiopeia A supernova
Toshiki Sato, Kai Matsunaga, Hiroyuki Uchida +10
Understanding stars and their evolution is a key goal of astronomical research and has long been a focus of human interest. In recent years, theorists have paid much attention to t…
