Abstract:
The Asymptotic Giant Branch stars, in particular those of carbon types, are excellent laboratories to constraint the theory of structure, evolution and nucleosynthesis of low mass stars. Despite the uncertainties still existing in the chemical analysis of these stars, the determination of the abundances of several key speciesin their atmospheres (lithium, carbon, fluorine and s-elements etc..) is an useful tool to test these theories and the mixing processes occurring inside these stars. I will briefly review recent advances on this subject.
