Force on proton vortices in superfluid and superconducting matter of neutron stars is calculated at vanishing stellar temperature. Both longitudinal (dissipative) and transverse (Lorentz-type) components of the force are derived in a coherent way and compared in detail with the corresponding expressions available in the literature. This allows us to resolve a controversy about the form of the Lorentz-type force component acting on proton vortices. The calculated force is a key ingredient in magnetohydrodynamics of superconducting neutron stars and is important for modeling the evolution of stellar magnetic field.

  1. Neutron contribution to the force on a proton vortex in superconducting neutron-star matter

    astro-ph.HE 2026-07 conditional novelty 7.0 of 10

    Normal neutrons scatter off proton vortices via the spatially varying condensate momentum, producing a purely longitudinal force proportional to relative neutron-vortex velocity that vanishes without neutron-proton Fe...

  2. Non-purely transverse Magnus force in superconducting neutron stars

    astro-ph.HE 2025-05 conditional novelty 6.0 of 10

    In the idealized extreme type-II limit, the force on a proton vortex core is exactly the Magnus force evaluated with a corrected local proton current, yielding a longitudinal force component usually omitted.
