Comprehensive neutrino light curves and spectra: from pre-supernova evolution to early supernova phase
Chinami Kato, Hiroki Nagakura, Akira Ito +4
We present the first systematic study of neutrino emissions from massive stars, continuously tracking the late evolutionary stages through the early core-collapse supernova phase.…
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…
Extreme anisotropies in deep layers of an exploding star: overabundance of Cr in the northeastern jet of Cassiopeia A
Vincenzo Sapienza, Marco Miceli, Masaomi Ono +5
Core-collapse supernovae drive nucleosynthesis under extreme thermodynamic conditions, and complex mechanisms are at work prompting the transport of heavy elements from deep stella…
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…
