Explosive Nucleosynthesis in Hypernovae
Takayoshi Nakamura, Hideyuki Umeda, Koichi Iwamoto +4
We examine the characteristics of nucleosynthesis in 'hypernovae', i.e., supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs). We carry out detailed nucleosynthes…
A Spectroscopic Analysis of the Energetic Type Ic `Hypernova' SN 1997ef
Paolo A. Mazzali, Koichi Iwamoto, Ken'ichi Nomoto
The properties of the bright and energetic Type Ic SN 1997ef are investigated using a Monte Carlo spectrum synthesis code. Analysis of the earliest spectra is used to determine the…
A Model for the Quiescent Phase of the Recurrent Nova U Scorpii
Izumi Hachisu, Mariko Kato, Taichi Kato +2
A theoretical light curve is constructed for the quiescent phase of the recurrent nova U Scorpii in order to resolve the existing distance discrepancy between the outbursts (6 kpc)…
