Abstract
- The study of post‐AGB stars gives important informations on the s‐process inside AGB stars, as the s‐enrichment of post‐AGB stars is due to an intrinsic process. A sample of thirteen C‐and s‐rich post‐AGB stars were analyzed with AGB nucleosynthetic models at different masses, metallicities and s‐process efficiencies. We present and discuss the theoretical fits obtained for 3 selected stars of our sample. A summary of the results obtained by comparing spectroscopic abundances and AGB theoretical models for all the considered stars is reported.
