Abstract.

We investigate the evolution of low-mass metal-free Population III stars accounting for the most updated physical inputs and for atomic diffusion. In particular, we test the efficiency of pollution by the encounter with gas clouds, combined with particle diffusion, in order to verify if such mechanism could be a relevant external source of CNO-elements. The possibilities to discriminate between a Pop II and a polluted Pop III field star are also briefly discussed.
