Chemical Evolution of Odd Elements in an Inhomogeneous Early Galaxy
Takuji Tsujimoto, Toshikazu Shigeyama, Yuzuru Yoshii
We investigate the chemical evolution of odd-numbered elements such as sodium (Na) and aluminum (Al) during the early epochs of the Galactic halo with the use of a model that repro…
Supernova SN1987A Revisited as a Major Production Site for r-Process Elements
Takuji Tsujimoto, Toshikazu Shigeyama
The origin of nucleosynthesis products of rapid neutron capture reactions (the r-process) is a longstanding astrophysical problem. Recent analyses of elemental abundances for extre…
Cosmic Supernova Rate History and Type Ia Supernova Progenitors
Chiaki Kobayashi, Ken'ichi Nomoto, Takuji Tsujimoto
Adopting a single degenerate scenario for Type Ia supernova progenitors with the metallicity effect, we make a prediction of the cosmic supernova rate history as a composite of the…
