We study the effect of WIMP annihilation on the temperature of a neutron star. We shall argue that the released energy due to WIMP annihilation inside the neutron stars, might affect the temperature of stars older than 10 million years, flattening out the temperature at $\sim 10^4$ K for a typical neutron star.

  1. A self-consistent single-fluid framework for neutron stars admixed with mirror dark matter

    astro-ph.HE 2026-07 unverdicted novelty 7.0

    Mirror dark matter admixture via mutual mean-field shifts softens the nuclear EOS, raises central densities, lowers maximum masses, and moves the direct Urca onset to higher or lower masses depending on symmetry-energ...

  2. Asymmetric Cannibal Dark Matter: Constraints from Neutron Star

    hep-ph 2025-09 unverdicted novelty 7.0

    Asymmetric cannibal dark matter with Z3-symmetric 3→2 interactions depletes in neutron star cores, producing observable heating signatures that constrain dark matter parameters beyond standard annihilation models.

  3. Probing freeze-in dark matter using Bose-Einstein condensate in neutron star

    hep-ph 2026-05 unverdicted novelty 5.0

    Bose-Einstein condensate formation in neutron stars enhances dark matter annihilation by 10^15-10^20, allowing freeze-in models to produce observable heating and probe neutrino-fog scattering cross-sections.

  4. Neutron star with dark matter using vector portal

    hep-ph 2026-04 unverdicted novelty 5.0

    Vector portal fermionic dark matter admixed in neutron stars produces mediator-mass-dependent changes to the equation of state, yielding distinct mass-radius relations and tidal deformabilities that observations can u...

  5. Sub-GeV dark matter in neutron stars: halo morphologies and their suppression by vacuum-like pressure

    astro-ph.HE 2025-11 unverdicted novelty 5.0

    A small vacuum-like dark-energy admixture in neutron stars with 400 MeV–1 GeV fermionic dark matter shrinks halo-induced radius differences from several kilometers to sub-kilometer scales and mass differences to ≲1%.

  6. 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.

  7. Observables and conformal properties of dark matter admixed isentropic neutron stars

    hep-ph 2026-06 unverdicted novelty 4.0

    DM admixture in isentropic neutron stars can mimic quark-matter conformality signatures via competition between thermal effects and dark sector softening.

  8. Constraining dark matter self-interaction from kinetic heating in neutron stars

    hep-ph 2026-04 unverdicted novelty 4.0

    Observation of neutron stars at 1000-1200 K could constrain asymmetric dark matter self-interaction cross-sections by two orders of magnitude beyond bullet cluster limits.

  9. Muonphilic asymmetric dark matter at a future muon collider

    hep-ph 2025-12 unverdicted novelty 4.0

    Muonphilic portals to fermionic asymmetric dark matter are constrained by existing data and can be probed further by 3 and 10 TeV muon colliders.

  10. Thermal emission from dark matter-heated neutron stars in the Galactic Center

    astro-ph.HE 2026-06 unverdicted novelty 3.0

    DM-heated neutron stars in the Galactic Center reach equilibrium temperatures of 10^4-10^6 K but their emission is below detection thresholds due to extinction.
