    DETAILS

    The purpose of Galactic archaeology is to unveil the formation and evolution of our Galaxy by interpreting the observed chemical abundances and kinematics of resolved stellar populations. Chemical evolution models predict the evolution of the abundances of chemical elements in the interstellar medium (ISM) and then compare these predictions with the abundances measured in stars. To do this, one has to assume that the chemical abundances in the ISM, at a given time, are representing the composition of stars born at that same time. From this comparison, we can derive the typical timescales for the formation of the various Galactic components (halo, bulge, thick and thin disc). Therefore, the ages of stars are a very important parameter in the process of chemical evolution, and recently a great improvement in the derivation of stellar ages arose from asteroseismology. Knowing the stellar ages and chemical abundances at the same time has improved noticeably the predicting power of chemical models, and the interpretations of the observed abundance patterns.

    In this Conference, we will discuss how to derive stellar ages, by presenting all the available methods including isochrone fitting and asteroseismology, as well as chemical abundances in the era of the Large Galactic Spectroscopic Surveys. Particular attention will be devoted to the astroarchaeology of the Milky Way as well as of the galaxies of the Local Group.

    The main topics of the conference are:

    –Models of stellar evolution and variability

    –Stellar ages (asteroseismology and isochrone fitting)

    –Stellar spectroscopy

    –Stellar chemical yields

    –Chemical evolution models
