Query: The Role of Type Ia Supernovae in Chemical Evolution I: Lifetime of Type
  Ia Supernovae and Galactic Supernova Rates   We construct a new model of Type Ia Supernovae (SNe Ia), based on the single
degenerate scenario, taking account of the metallicity dependences of the white
dwarf (WD) wind and the mass-stripping effect on the binary companion star. Our
model naturally predicts that the SN Ia lifetime distribution spans a range of
0.1-20 Gyr with the double peaks at ~0.1 and 1 Gyr. While the present SN Ia
rate in elliptical galaxies can be reproduced with the old population of the
red-giants+WD systems, the large SN Ia rate in radio galaxies could be
explained with the young population of the main-sequence+WD systems. Because of
the metallicity effect, i.e., because of the lack of winds from WDs in the
binary systems, the SN Ia rate in the systems with [Fe/H]<-1, e.g., high-z
spiral galaxies, is supposed to be very small. Our SN Ia model can give better
reproduction of the [(alpha, Mn, Zn)/Fe]-[Fe/H] relations in the solar
neighborhood than other models such as the double-degenerate scenario. The
metallicity effect is more strongly required in the presence of the young
population of SNe Ia. We also succeed in reproducing the galactic supernova
rates with their dependence on the morphological type of galaxies, and the
cosmic SN Ia rate history with a peak at z~1. At z>1, the predicted SN Ia rate
decreases toward higher redshifts and SNe Ia will be observed only in the
systems that have evolved with a short timescale of chemical enrichment. This
suggests that the evolution effect in the supernova cosmology can be small.
