I will provide an overview of processes that produce chemical elements in the Universe, from big bang nucleosynthesis to stellar element production in various stages of a star evolution. The processed material is returned to the interstellar medium that forms new stellar generations.
We can measure stellar abundances and with chemical evolution models we can reconstruct what types of stars contributed to the formation of a stellar system or a galaxy, and the timescales. This is often called Galactic Archaeology when applied to the Milky Way, because stellar chemical abundance ratios of can be used as fossil records to recover the past of the Galaxy.
