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…
Evidence for Type Ib/c origin of the supernova remnant G292.0+1.8
Takuto Narita, Hiroyuki Uchida, Jacco Vink +6
Circumstellar material (CSM) produced by mass loss from massive stars () through strong stellar winds or binary stripping provides rich information for underst…
Progenitor Constraint Incorporating Shell Merger: The Case of Supernova Remnant G359.0-0.9
Kai Matsunaga, Hiroyuki Uchida, Rei Enokiya +5
It is generally hard to put robust constraints on progenitor masses of supernovae (SNe) and remnants (SNRs) observationally, while they offer tantalizing clues to understanding exp…
Destratification in the Progenitor Interior of the Mg-rich Supernova Remnant N49B
Toshiki Sato, Kai Matsunaga, Ryo Sawada +6
Simulations of pre-supernova evolution suggest that some intense shell burning can be so active that, in extreme cases, it can merge with the outer shell, changing the initial cond…
Explosive Nucleosynthesis of Weak r-Process Elements in Extremely Metal-Poor Core-Collapse Supernovae
N. Izutani, H. Umeda, N. Tominaga
There have been attempts to fit the abundance patterns of extremely metal-poor stars with supernova nucleosynthesis models for the lighter elements than Zn. On the other hand, obse…
Hypernovae and Other Black-Hole-Forming Supernovae
K. Nomoto, K. Maeda, P. A. Mazzali +3
During the last few years, a number of exceptional core-collapse supernovae (SNe) have been discovered. Their kinetic energy of the explosions are larger by more than an order of m…
Hypernova Nucleosynthesis and Galactic Chemical Evolution
K. Nomoto, K. Maeda, H. Umeda +1
We study nucleosynthesis in 'hypernovae', i.e., supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs) for both spherical and aspherical explosions. The hypernova y…
Influence of the Stellar Population on Type Ia Supernovae: Consequences for the Determination of Omega
P. Höflich, K. Nomoto, H. Umeda +1
The influence of the metallicity at the main sequence on the chemical structure of the exploding white dwarf, the nucleosynthesis during the explosion and the light curves of an in…
