Abstract

The AMBRE Spectral Library comprises the archived spectra of the FEROS, HARPS and UVES ESO spectrographs and their stellar parameters derived by automatic parameterisation. With this extensive set of stellar parameters and radial velocities, analyses regarding element abundances has been carried out, enriching this dataset further. Initial projects regarding Lithium and Iron-peak abundances in the galactic disk showcase the usefulness of this library. The cross-match of the objects within the AMBRE Spectra Library with the Gaia first release of the parallaxes for the Tycho 2 catalogue (TGAS) have proved a key resource in investigating the chemical distribution of the Gaia galactic populations.
