WIMP Annihilation and Cooling of Neutron Stars
read the original abstract
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.

Asymmetric Cannibal Dark Matter: Constraints from Neutron Star
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.

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

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