Nucleosynthesis of Mo and Ru isotopes in neutrino-driven winds

The solar system origin of the p-isotopes ⁹²,⁹⁴Mo and ⁹⁶,⁹⁸Ru is a long-lasting mystery. Several astrophysical scenarios failed to explain their formation. Moreover, SiC X grains show a different abundance ratio of ⁹⁵,⁹⁷Mo than in the solar system. We have investigated if neutrino-driven winds can offer a solution to those problems.
