The RAVE harvest: from the relation between abundances and kinematic of the Milky Way stars to tools for the abundance analysis of the spectra

摘要

RAVE is a spectroscopic survey of the Milky Way which collected more than500,000 stellar spectra of nearby stars in the Galaxy. The RAVE consortiumanalysed these spectra to obtain radial velocities, stellar parameters andchemical abundances. These data, together with spatial and kinematicinformation like positions, proper motions, and distance estimations, make theRAVE database a rich source for galactic archaeology. I present recentinvestigations on the chemo-kinematic relations and chemical gradients in theMilky Way disk by using RAVE data and compare our results with the Besanconmodels. I also present the code SPACE, an evolution of the RAVE chemicalpipeline, which integrates the measurements of stellar parameters and chemicalabundances in one single process.
