Abstract
Investigation of the assembly history of the Milky Way and its closest satellites. Aim of the project is to reconstruct the assembly history of the Milky Way and its satellites, using the chemical abundances of their stars as inferred from high-resolution spectroscopy. An important fraction of the stars populating the Galactic Halo were accreted from disrupted satellited and the use of chemical tagging is a powerful tool to reconstruct the nature of these building block of our galaxy, also with the comparison with other survived close systems. The main goals are: (1) chemical characterization of the stellar populations in three closest Milky Way's satellites, namely the Large and Small Magellanic Clouds, and the Sagittarius dwarf galaxy. (2) chemical description of Galactic stars selected according to their dynamical properties, in particular candidate in-situ and accreted stars; (3) comparison between the chemical properties of accreted stars in the Galctic halo and in the Milky Way's satellites; (4) development of new chemical evolution models to describe the chemical patterns of all the investigated galaxies.
