The limiting rotational frequency of neutron stars may be determined by the strength of their crusts. As a star spins up from accretion, centrifugal forces will cause the crust to fail. If the crust breaks unevenly, a rotating mass quadrupole moment will radiate gravitational waves (GW). This radiation can prevent further spin up and may be a promising source for continuous GW searches. We calculate that for a breaking strain (strength) of neutron star crust that is consistent with molecular dynamics simulations, the crust may fail at rotational frequencies in agreement with observations.

  1. Investigating field burial by magnetically confined accretion mounds on Neutron Stars

    astro-ph.HE 2025-07 conditional novelty 7.0 of 10

    Accretion mounds on neutron stars spread equator-ward as their mass grows, measurably burying the dipole field for low-field stars, and a new current-free boundary condition removes dependence on the outer domain size.
