Stellar Evolution: Open and Globular Clusters

Georges Michaud

Université de Montréal

Evolutionary models taking into account diffusive processes for all important atomic species (28) have been computed for stars of Pop I and II. I will briefly present them and will use them to discuss a number of properties of open (AmFm stars, isochrones, convective cores) and globular clusters (turnoff, horizontal branch, ages). Applications will be made to interpretation of results from WMAP on lithium.
