Scientific paper

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.
