Cosmic supernova rate history and Type Ia supernova progenitors
Nomoto, K; Tsujimoto, T; Kobayashi, Chiaki (World Scientific Publishing, 2001)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 supernova rates in spiral and elliptical ... -
Cosmic supernova rates in cluster vs. field galaxies
Kobayashi, Chiaki; Tsujimoto, T; Nomoto, K (1999) -
Explosive nucleosynthesis in massive Pop III stars and abundances in metal-poor stars and M87
Shirouzu, M; Kobayashi, Chiaki; Umeda, H; Nomoto, K (Astronomical Society of the Pacific, 2001)In order to understand the elemental abundance pattern observed in galaxies and clusters of galaxies of various metallicity, we investigate stability, evolution and explosion of massive population III stars. We find the ... -
The history of the cosmic supernova rate derived from the evolution of the host galaxies
Kobayashi, C; Tsujimoto, T; Nomoto, K; Kobayashi, Chiaki (2000-08-10)Ne make a prediction of the cosmic supernova rate history as a composite of the supernova rates in spiral and elliptical galaxies. Ne include the metallicity effect on the evolution of Type Ia supernova (SN Ia) progenitors ... -
Low-metallicity inhibition of type Ia supernovae and galactic and cosmic chemical evolution
Kobayashi, Chiaki; Tsujimoto, T; Nomoto, K; Hachisu, I; Kato, M (1998-08-20)We introduce a metallicity dependence of the Type Ia supernova (SN Ia) rate into the Galactic and cosmic chemical evolution models. In our SN Ia progenitor scenario, the accreting white dwarf (WD) blows a strong wind to ... -
Metallicity effect on type Ia supernovae and galactic and cosmic chemical evolution
Kobayashi, Chiaki; Tsujimoto, T; Nomoto, K (Springer Nature, 2000) -
The origin of the diversity of Type Ia supernovae and the environmental effects
Umeda, H; Nomoto, K; Kobayashi, Chiaki; Hachisu, I; Kato, M (1999-09-01)Observations suggest that the properties of Type Ia supernovae (SNe Ia) may depend on environmental characteristics, such as the morphology, metallicity, and age of the host galaxies. The influence of these environmental ... -
Supernova nucleosynthesis, chemical evolution, and cosmic supernova rate
Nomoto, K; Nakamura, T; Kobayashi, Chiaki (1999)In the chemical evolution of the Galaxy, Type II supernovae (SNe II) have contributed to the early metal enrichment and later Type Ia supernovae (SNe Ia) have contributed to the delayed enrichment of Fe. In principle, ... -
Type Ia supernovae and chemical evolution of galaxies
Nomoto, K; Umeda, H; Kobayashi, Chiaki (Kluwer, 2002)The cosmic/galactic chemical evolutions have been modeled with the early metal enrichment by Type II supernovae (SNe II) and the delayed enrichment of Fe by Type Ia supernovae (SNe Ia). However, the exact nature of SN Ia ... -
Type Ia supernovae: Progenitors and evolution with redshift
Nomoto, K; Umeda, H; Hachisu, I; Kato, M; Tsujimoto, T; Kobayashi, Chiaki (American Institute of Physics (AIP), 2000)Relatively uniform light curves and spectral evolution of Type Ia supernovae (SNe Ia) have led to the use of SNe Ia as a "standard candle" to determine cosmological parameters. Whether a statistically significant value of ...
