摘要
We present open chemical evolution models of the local Galactic disk which take into account stellar yields, lifetimes, remnant masses, and supernova originator masses dependent on the initial metallicity of the progenitor clouds. We use two types of initial mass function. We have followed the detailed evolution of some single elements H, HE-4, C-12, O-16, FE-and of the heavy elements of metallicity Z dropping the instantaneous recycling approximation. Using the Scalo initial mass function and two classes of Type Ib supernova progenitors, Wolf-Rayet stars and binary systems, our results reproduce the majority of the observationaL constraints, such as the frequency of supernova explosions, gas mass, solar abundance and solar age, abundances of field stars, distribution of G dwarfs, and the age-iron relation.
