Abstract

Unevolved or scarcely evolved stars of globular clusters do not have either high enough temperatures in their cores or large enough convective envelopes to dredge up to the surface the products of high temperature proton-capture reactions. Hence, these stars represent an ideal diagnostic to study the pattern of the chemical anomalies observed in the C, N, O, Na, Mg, Al elements. I will review the status of researches on this presently debated subject, presenting also the latest results from high resolution UVES spectra on dwarf and subgiant stars in NGC 6397, NGC 6752 and 47 Tuc.
