Description
Despite considerable progresses over the past decades, the origin of trans-iron elements is not yet fully understood. In addition to the slow (s) and rapid (r) neutron capture processes, an intermediate neutron capture process (i-process) is thought to exist at neutron densities intermediate between the s- and r-processes. The isotopic signature of some pre-solar grains and the chemical composition of the so-called r/s-stars support the existence of this process but the astrophysical site(s) hosting the i-process is (are) actively debated. The early AGB phase of low-mass stars is a promising site. In this presentation, I will focus on the development of the i-process in state-of-the-art AGB stellar models computed with the STAREVOL code. I will pay special attention to the chemical fingerprint of these stars, and show that they can produce some short-lived radionuclides.
