Scientific paper

The characterizing features of primordial stars are described, and the chemical yields of C, O and Fe are derived. These yields, together with the correspondent ones for young stars, are used to study the history of production of C, O and Fe in the galactic disk. This makes it possible to put constraints on the chemical enrichment in the first stellar generations, and to account for the oxygen overabundance observed in metal-poor stars. Finally, some information on the initial mass function for primordial stars is derived.
