Abstract

The author presents techniques for generating exact solutions to the differential equations for the chemical evolution of galactic gas MG(t), the star mass S(t), the metallicity Z(t), and the abundances of the radioactive chronometers Zlambda(t) in the face of galactic infall f(t). The author assumes instantaneous recycling and a linear dependence of star formation rate upon gas mass. Because some of these solutions are simple analytic functions, they can serve as standard models for the usual tests of galactic evolution. This paper emphasizes cases where infall f(t) terminates at some time t0 and is zero thereafter.
