Supernovae neutrinos and the r-process and ν-processes of nucleosynthesis Original Research Article

The neutrinos emitted from supernovae contain information both about the physics of stellar collapse and of the nature of the neutrinos. Several detectors exist that will be capable of observing some subset of those neutrinos. To complement these detectors, we have designed OMNIS, the Observatory for Multiflavor NeutrInos from Supernovae. OMNIS will provide new information on stellar collapse and neutrino transformations, possibly diagnose the process of collapse to a black hole, and observe the late-time evolution of the neutrino distributions. OMNISʹ ability to measure the spectra of the neutrinos will have an important effect on our understanding of the r- and ν-processes of nucleosynthesis. OMNIS is also sensitive to some modes of nucleon decay that could significantly improve present limits.
