Description
Red giant stars, both in the field and in globular clusters, present abundance anomalies that can not be explained by standard stellar evolution models. Some of these peculiarities clearly point towards the existence of extra-mixing processes at play inside the stars, the nature of which remains unclear. We present new results of the evolution of a typical globular cluster red giant including a fully consistent treatment of rotation-induced mixing from the ZAMS up to the RGB tip. The uncertainties pertaining to the prescriptions of angular momentum and chemicals transport inside the star are discussed.
