Scientific paper

The lack of self consistency in the current wind accretion models is pointed out. Combined with wind accretion scenarios, calculations of nucleosynthesis for intrinsic AGB stars are first used to calculate s-process enrichments of Ba stars. Comparisons are also made between the predictions of calculations and observations. It is found that predictions from the model for the standard case are an upper limit to the observations.
