Measurements of neutron star mass and radius or tidal deformability deliver unique insight into the equation of state (EOS) of cold dense matter. EOS inference is very often done using generalized parametric or non-parametric models which deliver no information on composition. In this paper we consider a microscopic nuclear EOS model based on a field theoretical approach. We show that current measurements from NICER and gravitational wave observations constrain primarily the symmetric nuclear matter EOS. We then explore what could be delivered by measurements of mass and radius at the level anticipated for future large-area X-ray timing telescopes. These should be able to place very strong limits on the symmetric nuclear matter EOS, in addition to constraining the nuclear symmetry energy that determines the proton fraction inside the neutron star.

  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. Bayesian inferences on covariant density functionals from multimessenger astrophysical data: The impacts of likelihood functions of low density matter constraints

    nucl-th 2025-05 conditional novelty 5.0 of 10

    Using a uniform instead of Gaussian likelihood for low-density nuclear constraints leaves neutron star radii and masses nearly unchanged, but shifts the inferred nuclear incompressibility.

  4. Exploring the limits of nucleonic metamodelling using different relativistic density functionals

    nucl-th 2025-02 conditional novelty 5.0 of 10

    Comparing two relativistic mean-field model families, the paper shows beta-equilibrium neutron star observations constrain the equation of state but not the proton fraction.

  5. Bayesian constraints on covariant density functional equations of state of compact stars with new NICER mass-radius measurements

    hep-ph 2024-12 conditional novelty 5.0 of 10

    Bayesian fits that include the 2024 NICER results for PSR J0437 and J1231 narrow the allowed radius range for canonical-mass neutron stars to roughly 12.5 to 12.8 km in covariant density functional models.

  6. Effects of dark matter and magnetic field on neutron star properties in relativistic mean-field theory: A single-fluid approach

    astro-ph.HE 2026-07 conditional novelty 4.0 of 10

    Fermionic dark matter and strong central magnetic fields both reduce neutron-star maximum mass and radius and lower tidal deformability in single-fluid RMF models, remaining compatible with GW/NICER constraints over t...

  7. Crust (Unified) Tool for Equation-of-state Reconstruction (CUTER) v2

    astro-ph.HE 2025-06 accept novelty 4.0 of 10

    CUTER v2 reconstructs the missing or inconsistent low-density crust of arbitrary neutron-star equations of state, producing unified EoSs whose global properties match original models to within about one percent.
