Sub-GeV neutrinos produced in a stellar core may emerge from main sequence stars, white dwarfs and brown dwarfs producing possible observable signals of dark matter capture. A distribution of these stars near the Milky Way galactic center will produce a neutrino flux that can be probed at Earth based neutrino observatories like Super-Kamiokande and Hyper-Kamiokande. We demonstrate that this can provide a handle to probe dark matter masses in the $200\,$MeV\,$-$\,$2\,$GeV mass scales that compares favourably with present day direct detection bounds.

    hep-ph 2026-07 conditional novelty 6.0

    Repeated collapse of asymmetric dark matter inside neutron stars into evaporating microscopic black holes can produce a Galactic-Center-concentrated high-energy neutrino flux at the 10^-12 GeV cm^-2 s^-1 level, subdom...

  2. High-Energy Neutrinos from Black Hole Evaporation in Neutron Stars

    hep-ph 2026-07 conditional novelty 6.0

    Dark matter collapsing inside neutron stars could repeatedly form microscopic black holes whose Hawking evaporation produces a detectable high-energy neutrino flux concentrated toward the Galactic Center.

  3. Super-Kamiokande Strongly Constrains Leptophilic Dark Matter Capture in the Sun

    astro-ph.HE 2025-01 unverdicted novelty 5.0

    Super-Kamiokande data constrains the DM-electron scattering cross-section for leptophilic dark matter to ~4e-41 cm2 below 100 GeV, exceeding direct detection by over an order of magnitude.
