We explore the synthesis of s-process elements during the formation of He-rich sdO/Bs and the emergence of these elements at the surface, with a recently developed post-processing code of detailed stellar nucleosynthesis. The sutdy of the detailed nucleosynthesis on He-rich sdO/Bs can shed light on the formation history of these objects, that is not well understood yet. In this first study, we focus on the hot-flasher scenario. We present here preliminary results.
