Using time-of-flight delays of the three neutrino mass eigenstates across sharp supernova features, a galactic supernova at 10 kpc could individually constrain or measure neutrino masses at JUNO, with precision that depends strongly on the assumed mass scale.

abstract
General relativistic multi-group and multi-flavor Boltzmann neutrino transport in spherical symmetry adds a new level of detail to the numerical bridge between microscopic nuclear and weak interaction physics and the macroscopic evolution of the astrophysical object. Although no supernova explosions are obtained, we investigate the neutrino luminosities in various phases of the postbounce evolution for a wide range of progenitor stars between 13 and 40 solar masses. The signal probes the dynamics of material layered in and around the protoneutron star and is, within narrow limits, sensitive to improvements in the weak interaction physics. Only changes that dramatically exceed physical limitations allow experiments with exploding models. We discuss the differences in the neutrino signal and find the electron fraction in the innermost ejecta to exceed 0.5 as a consequence of thermal balance and weak equilibrium at the masscut.

Individual Neutrino Masses From a Supernova
Using time-of-flight delays of the three neutrino mass eigenstates across sharp supernova features, a galactic supernova at 10 kpc could individually constrain or measure neutrino masses at JUNO, with precision that depends strongly on the assumed mass scale.
