In magnetorotational stellar collapses, neutrinos undergo resonant flavor conversion in matter plus magnetic-moment-driven chirality flipping for Majorana neutrinos, producing orientation-dependent event rates at detectors that peak 400-600 ms after bounce.

abstract
We calculate rates of flavor exchange within clouds of neutrinos interacting with each other through the standard model coupling, assuming a conventional mass matrix. For cases in which there is an angular dependence in the relation among intensity, flavor and spectrum, we find instabilities in the evolution equations and greatly speeded-up flavor exchange. The instabilities are categorized by examining linear perturbations to simple solutions, and their effects are exhibited in complete numerical solutions to the system. The application is to the region just under the neutrino surfaces in the supernova core.

Fast flavor conversion of neutrinos bifurcates supernova explosion outcomes: it aids shock revival in low-mass progenitors but inhibits it in higher-mass ones, controlled by mass accretion rate.
MSW resonances in collapsing supermassive stars swap neutrino flavors adiabatically in the normal hierarchy for neutrinos and inverted hierarchy for antineutrinos, altering the initial 5:1 electron-to-muon/tau flux ratio.
