    • 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 ...

    • 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 ...

    • 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 ...
