Descrizione
High-resolution stellar spectroscopy, combined with precise astrometry from Gaia, has revolutionized our understanding of both the formation and evolution of the Milky Way and stellar nucleosynthesis. In this talk, I will present recent progress in mapping the Galaxy’s large-scale chemical structure over time, including radial metallicity gradients and spiral patterns, and explore how stellar chemical compositions relate to planetary system architectures. I will also discuss detailed abundance measurements of heavy elements and their isotopes, providing key insights into nucleosynthetic processes from the lightest to the heaviest elements. Finally, I will outline future perspectives, with particular emphasis on the proposed ESO high-resolution multi-object spectrograph HRMOS, and its potential to advance studies ranging from exoplanet populations and precise stellar age determinations to the detailed chemical history of the Galaxy and its satellites.
