Nucleosynthesis and Chemical Evolution from Las Campanas Observatory
Las Campanas observatory houses two of the largest optical telescopes in the world. Coupled with an efficient high-resolution spectrograph, these telescopes permit detailed chemical abundance measurements of individual stars in the nearest members of the Local Group of galaxies.
I discuss a few ways in which the chemical composition of the envelopes of old stars provides constraints on the astrophysical sites of nucleogenesis, stellar structure and evolution, and the evolution of galaxies.
