Description

Since the second half of last century, stellar evolution theory has allowed to
understand the Color Magnitude Diagram of galactic star clusters, so that now
we can explain the distribution of stars in the observed CMDs in terms of the nuclear
evolution of stellar structures and, thus, in terms of cluster age and chemical composition.
In the last decades, however, the impressive amount of data collected by photometric, astrometric,
spectroscopic and asteroseismic surveys is providing a detailed observational framework which
provides at the same time a stringent test and a challenge for the accuracy of the models.
In the same time, these stellar models are a crucial input for asteroseismology as well
as Galactic archeology studies. In this talk, we discuss (some of) the main uncertainties affecting stellar models and
how they critically impact on our capability to reliably unveil the chrono-chemo-dynamical
structure of the Galaxy.

  • The complex Milky Way history

    In this seminar I will focus on how the avalanche of new data changes our views on how our Galaxy formed and evolved. Precise astrometric, spectroscopic, photometric and asteroseismic data can be combined to pin down different processes that have shaped the Milky Way. This data will be discussed and illustrated with examples of what is possible to

  • Sounding the treasure trove - Asteroseismology of red-giant stars and binaries systems

    Understanding stellar structure and evolution significantly impacts our understanding of the tight-knit evolution of galaxies and exoplanet systems. However, hidden behind the luminous layers of the stellar atmosphere, the deep interior of a star is eluding from direct measurements. The seismic study of waves propagating the deep interior provides

  • The emergence of the Milky Way: Latest results from Galactic Archaeology

    The previous years have witnessed a big leap forward in our understanding of the Milky Way. Thanks to the highly accurate astrometry and photometry provided by the Gaia mission in combination with large photometric and spectroscopic all-sky surveys, we have now a clearer view of the chemo-dynamics of the stellar populations that constitute our
