Abundance gradients to trace galaxy formationand evolution : the Galactic disk

• Abundance gradients are one of the few observables constraining the chemo-dynamical models of the Milky Way disk. Here, we review recent improvements regarding the determination of chemical abundances of young stellar systems, Cepheids, and RGB stars, that are used to trace abundance gradients, before focusing on the oxygen gradient.
