This project will deliver a benchmark sample of stellar abundances for galactic archaeology for hundreds of thousands of stars. This project will first “betterize” the GALAH spectra and then apply the newest analysis approaches to derive abundances. We will then use these measurements to undertake a comprehensive analysis of the value of individual elements and how they capture the mixing timescales of element production and mixing scales in the Milky Way disk.
