Phylogeny of stars and the evolution of the Milky Way

Paula Jofre , Chile
Chemical elements are produced by stars, making stellar generations always more metal-rich with time. Hence, stellar generations pass information from one to the other one via their chemical compositions. This information provides a fundament for the motivation to create a spectroscopic survey of stars in the Milky Way. The chemical composition of thousands of stars, combined with their dynamical properties and their ages, serve to constrain the models of formation and evolution of our Galaxy. In this talk, I will first review the state-of-the art of the precision and accuracy of such industrial stellar abundance measurements. Then I will present a novel method to visualise and interpret these datasets, which is based on phylogenetic trees, and has been so far tested in a dataset of higher precision and accuracy.
