Abstract

Two examples of stellar predictions from models of asymptotic giant branch (AGB)stars are presented to illustrate the difficulties associated withastronuclear studies. The first example is the dredge-up process by whichnuclei synthesized in the stellar interior are brought to thesurface; the second is the production of primary sodium. Those examplesillustrate the need for a good understanding of the detailsof model calculations from both a physical and a numerical stand point.They highlight as well some of the current limitations of AGB modelpredictions.
