Galactic Chemical Evolution: Hydrogen Through Zinc

摘要: Using the output from a grid of 60 Type II supernova models (Woosley \& Weaver 1994) varying mass (11 $\ltaprx$ M/M\sun 40) and metallicity (0, 10$^{-4}$, 0.01, 0.1, 1 Z\sol), chemical evolution 76 stable isotopes, hydrogen to zinc, is calculated. The calculation employs simple dynamical model for Galaxy (infall with 4 billion year $e$-folding time scale onto exponential disk 1/r$^2$ bulge), standard parameters, such as Salpeter initial function quadratic Schmidt star formation rate. theoretical results are compared in detail observed stellar abundances stars metallicities range -3.0 [Fe/H] 0.0 dex. While our discussion focuses on solar neighborhood where there most observations, supernovae rates, an intrinsically Galactic quantity, also discussed.
