In our work we investigate the stellar surface fluxes of different neutrino flavors, both with and without matter effects, while aiming to consider the varying density of the progenitor star to reveal intriguing variations in their behavior. By examining both normal and inverted neutrino mass hierarchies in studies of neutrino fluxes, a behavioral difference is detected which highlights the significance of the chosen mass hierarchy for studies in understanding the neutrino oscillation phenomena. This difference in flux behavior also serves as a clue to probe the mass hierarchy; within the energy range of 13–19 meV, the neutrino mass hierarchy can be determined as normal or inverted by detecting excess or missing events in the non-electronic neutrinos. We also examine the level crossing diagrams of neutrinos to illustrate how different neutrino masses and energies affect the transformation of neutrino flavors as they propagate through matter with constant density. We determine the resonance regions (both high and low) with the highest flipping probability using the level crossing diagrams. This allows us to estimate where within a star we are most likely to find neutrino flavor conversions.
