Abstract
Direct evidence for collective neutrino oscillations in core-collapse supernovae remains elusive. We show that this quantum phenomenon leaves a footprint on the abundance pattern of proton-rich nuclides in the solar system. Modeling the nu p-process using a 20,M progenitor, we map out the dependence of the total yields on the starting radius of the oscillations, self-consistently coupling hydrodynamics and nucleosynthesis. The oscillations boost key p-nuclides (92,94 Mo, 96,98 Ru) and long-lived 92 Nb by up to two orders of magnitude, bringing their abundances into agreement with the observations. The best match is found when oscillations commence within 10 km of the proto-neutron star surface, indicating fast collective oscillations.
