We study the role that the future detection of the neutrino burst from a galactic supernova can play in the reconstruction of the neutrino mass spectrum. We consider all possible 3$\nu$ mass and flavor spectra which describe the solar and atmospheric neutrino data. For each of these spectra we find the observable effects of the supernova neutrino conversions both in the matter of the star and the earth. We show that studies of the electron neutrino and anineutrino spectra as well as observations of the neutral current effects from supernova will allow us (i) to identify the solar neutrino solution, (ii) to determine the type of mass hierarchy (normal or inverted) and (iii) to probe the mixing $|U_{e3}|^2$ to values as low as $10^{-4} - 10^{-3}$.

  5. Detection horizon for the neutrino burst from the stellar helium flash

    astro-ph.SR 2026-02 unverdicted novelty 5.0

    The helium flash produces a neutrino burst with a 1.7 MeV line detectable up to almost 3 pc in future facilities, but asteroseismology remains the practical probe for now.

    quant-ph 2026-06 unverdicted novelty 4.0

    Density matrix formalism supplies a general analytical solution for non-adiabatic transitions in two-state systems that interpolates between the LZSM regime and the extremely non-adiabatic limit.

  7. Impact of the equation of state on core collapse supernovae I: the low-$T/|W|$ instability
