Description
Neutrino-driven winds emerging after a successful core-collapse
supernovae can produce the lighter heavy elements between Fe and Ag depending on the
properties of the ejecta.
However, despite the fast progress in supernovae simulations in the last
decades, there are still large uncertainties in the astrophysical
conditions.
We rely on a steady-state neutrino-driven wind model to
systematically study the influence of astrophysical uncertainties on
the nucleosynthesis evolution in neutrino-driven ejecta.
Furthermore, uncertainties in the nuclear physic input to the
nucleosynthesis calculation impact the abundance patterns.
In order to identify key reactions, we perform sensitivity studies based on a
Monte Carlo approach for a variety of astrophysical conditions in neutron- and
proton-rich ejecta.
