Time-of-flight delay between oscillating neutrinos and gravitational waves from supernovae and the neutrino mass problem

Neutrino oscillations during core bounce of a supernova collapse may induce detectable gravitational-wave bursts by the time they are trapped in the core. For large-scale distances the flavor changing neutrinos get delayed on its trip to earth while the gravitational waves they emit do not. Since the oscillation mechanism sets up the offset for both emissions, this fact yields in a time-of-flight delay between both the radiations that, whenever measured, could provide an inedit estimative of the absolute scale of neutrino masses.
