Résumé :

In this conference talk I will discuss the new approach of the Besancon galaxy model to the interpretation of large spectroscopic surveys, and its contribution to understand the kinematics properties of canonical components of the Milky Way on the context of formation and evolution. I will also present the more relevant findings (Fernandez-Trincado 2016a, Fernandez-Trincado 2016b in prep.) carried out by our group, through the powerful method of chemical tagging which provide unique imprint in chemical abundance space, combined with accuracy 6D phase space information from Gaia mission and dynamical models we are able to trace the trajectory of stars in order to understand what happened in the Milky Way at earlier epochs.
