Dark matter (DM) may be captured around a neutron star (NS) through DM-nucleon interactions. We observe that the enhancement of such capturing is particularly significant when the DM velocity and/or momentum transfer depend on the DM-nucleon scattering cross-section. This could potentially lead to the formation of a black hole within the typical lifetime of the NS. As the black hole expands through the accretion of matter from the NS, it ultimately results in the collapse of the host. Utilizing the existing pulsar data J0437-4715 and J2124-3858, we derive the stringent constraints on the DM-nucleon scattering cross-section across a broad range of DM masses.

  1. Can Orbital Decay of Accreting Binary Pulsars Probe Dark Matter?

    hep-ph 2025-07 conditional novelty 5.0 of 10

    Dark matter accretion onto binary pulsars is far too weak to affect observed orbital decay, so existing pulsar timing data cannot probe dark matter microphysics.
