In core-collapse supernovae, the neutrino density is high enough to make the effects of nu-nu interaction important. Neutrinos couple, inducing collective flavor changes. The most striking effects would be abrupt changes in the neutrino energy spectra (spectral splits) according to the neutrino mass hierarchy. We explain the occurrence of spectral splits in a three-flavor framework.
