The equation of state and composition of the inner crust of neutron stars at zero temperature are calculated, using the T = 0 version of the TETFSI (temperature-dependent extended Thomas-Fermi plus Strutinsky integral) method, for each of a family of three functionals based on Skyrme-type forces BSk19, BSk20 and BSk21, which are characterized by different degrees of symmetry-energy stiffness, and also for the SLy4 functional. We also solve the Tolman-Oppenheimer-Volkoff equations to calculate the distribution of mass within the inner crust. Qualitatively similar results are found for all four functionals, and in particular the number of protons per Wigner-Seitz cell is in all cases equal to 40 throughout the inner crust.

  1. Neutron stars can shine a light on elusive lepton-flavor-violating dark matter

    hep-ph 2025-11 conditional novelty 7.0 of 10

    Flavor blocking keeps lepton-flavor-violating dark matter from thermalizing inside neutron stars, so p-wave annihilation stays efficient and heats the star to observable temperatures.

  2. Dark Matter Heating of Compact Stars Beyond Capture: A Relativistic Framework for Energy Deposition by Particle Beams

    hep-ph 2026-02 conditional novelty 6.0 of 10

    A new relativistic formalism computes capture and energy deposition of directed particle beams in compact stars, applied to blazar-boosted dark matter heating of white dwarfs and neutron stars.

  3. On variational trial functions in the extended Thomas-Fermi method

    nucl-th 2024-11 accept novelty 6.0 of 10

    A kink in the trial nucleon density at the center of cylindrical or plane-parallel Wigner-Seitz cells makes the fourth-order extended Thomas-Fermi energy divergent; only spherical-cell kinks are harmless.
