The delayed contribution of low and intermediate mass stars to chemical galactic enrichment: An analytical approach

open access: yes, 2008
We find a new analytical solution for the chemical evolution equations, taking into account the delayed contribution of all low and intermediate mass stars (LIMS) as one representative star that enriches the interstellar medium.This solution is built ...
