The AMBRE Project: chemical tagging of the Galactic disc

Patrick de Laverny
Observatoire de la Côte d'Azur, Nice, France

From the parametrisation of ESO archive spectra, the AMBRE Projet has chemically characterized about 7,000 stars in lithium, iron and alpha-element abundances and, for ~5,000 of them, their abundances in Mn, Ni, Cu, Zn have also been derived.
From this sample, we have derived information about the different chemical histories of the thin and thick discs. Some comparisons with current chemical models of the Milky Way reveal strong disagreements probably caused by uncertain stellar yields and different chemical histories in both discs.
