Dark matter seeding and the kinematics and rotation of neutron stars
  Self-annihilation of dark matter accreted from the galactic halo in the inner regions of neutron stars may affect their kinematical properties, namely velocity kicks and rotation patterns. We find that if a stable long-lived single or multiple strangelet off-center seed forms, there is an associated change in momentum and torque that may affect the kinematical observables of the star.
