Scientific paper

The history of the chemical composition of the Galaxy is dominated by the nucleosynthesis occurring in many generations of stars. Very metal-poor stars represent one of the main diagnostic tools to probe the earliest phases of the chemical evolution of our Galaxy. Any variation in the elemental abundance ratios observed at different metallicites can then be compared with the yields derived from SNe of different masses to determine which ones have contributed to the Galactic chemical enrichment and when. Here, the preliminary result of a recent analysis that has focused on the iron-group element copper is presented, which has the main goal of better constraining its nucleosynthetic origin.
