The role of radial migration and of a new grid of stellar yields in the chemical evolution of the Milky Way


I will present an overview of the potential impact of radial migration on the chemical evolution of the Milky Way disk, based on the results of N-body simulations and semi-analytical models. I will discuss, in particular, the impact on local observables (the local age-metallicity relation and its dispersion, the local metallicity distribution etc.), as well as the chemical properties of the thin and thick disks. I will also present new results obtained with recent yields of rotating massive stars for all elements from C to Pb.
