Formation of the Neutron Donor C13 in AGB Stars by Overshoot and Rotation
Falk Herwig, Norbert Langer
(abridged) Observations clearly show that low-mass AGB stars can provide a nucleosynthesis site of the s-process. Recent stellar evolution models indicate that radiative burning of…

The evolution of AGB stars with convective overshoot
Falk Herwig
The influence of extended convective mixing (overshoot) on asymptotic giant branch stellar evolution is investigated in detail. The extended mixing is treated time-dependently, and…

AGB evolution with overshoot: hot bottom burning and dredge up
T. Bloecker, F. Herwig, T. Driebe
We calculated models of massive AGB stars with a self-consistent coupling of time-dependent mixing and nuclear burning for 30 isotopes and 74 reactions. Overshoot with an exponenti…
