Despite being a well understood phenomenon in the context of current terrestrial experiments, neutrino flavor conversions in dense astrophysical environments probably represent one of the most challenging open problems in neutrino physics. Apart from being theoretically interesting, such a problem has several phenomenological implications in cosmology and in astrophysics, including the primordial nucleosynthesis of light elements abundance and other cosmological observables, nucleosynthesis of heavy nuclei and the explosion of massive stars. In this review, we briefly summarize the state of the art on this topic, focusing on three environments: early universe, core-collapse supernovae and compact binary mergers.

  1. Predicting the outcome of collisional neutrino flavor conversion

    hep-ph 2025-05 conditional novelty 7.0 of 10

    Collisional neutrino flavor instabilities settle into a state at the edge of instability with nonzero flavor coherence, and explicit formulas predict this final state.

  2. Solar-System Abundances of $p$-Nuclides Probe Collective Neutrino Oscillations in Supernovae

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Nearby neutrino flavor conversion in a supernova can boost νp-process yields of p-nuclides like 92Mo and 92Nb by up to two orders of magnitude, matching solar abundances when conversion starts within ~10 km of the pro...

  3. Estimating amplitude of matter density fluctuations in solar and supernova models using neutrino flavor evolution

    astro-ph.HE 2026-07 conditional novelty 5.0 of 10

    SDA recovers density-fluctuation amplitudes from boundary neutrino flavor data in simplified solar and CCSN models, more reliably for the Sun and at high noise in CCSN.
