| Abstract: |
The occurrence of recursive thermonuclear runaways makes the computation
of AGB evolutionary sequences and the related nucleosynthesis a
challenging task for stellar modelers. In the last 20 years many efforts
have been made to improve the physical description of the interiors of
these stars. Nevertheless, the majority of the extant nucleosynthesis
results are based on post-process calculations, in which the evolution
of the nuclear network and that of the stellar structure are treated
separately and, hence, decoupled. In this paper, we review the latest
attempts made to obtain more reliable nucleosynthesis calculations
based on the physical processes expected to be at work in AGB stars,
such as the mixing induced by convection and rotation. |
