We investigate how current and proposed observations of neutron stars can lead to an understanding of the state of their interiors and the key unknowns: the typical neutron star radius and the neutron star maximum mass. A theoretical analysis of neutron star structure, including general relativistic limits to mass, compactness, and spin rates is made. We consider observations made not only with photons, ranging from radio waves to X-rays, but also those involving neutrinos and gravity waves. We detail how precision determinations of structural properties would lead to significant restrictions on the poorly understood equation of state near and beyond the equilibrium density of nuclear matter.

  1. Sensitivity of Neutron Star Observables to Transition Density in Hybrid Equation-of-State Models

    nucl-th 2026-04 accept novelty 5.0

    Hybrid neutron-star equations of state remain sensitive to the low-density nucleonic model at transition densities around 2ρ₀, with model spread in radius and tidal deformability exceeding observational uncertainty by...

    astro-ph.HE 2026-05 unverdicted novelty 4.0

    Significant X-ray flux blocking in 4U 1746-37 allows the neutron star to have canonical mass and radius values of 1.59 solar masses and 13 km or 2.12 solar masses and 9.8 km.

  3. Guitar Nebula: extreme accelerator in extreme environment

    astro-ph.HE 2026-05 unverdicted novelty 4.0

    The Guitar Nebula requires extreme acceleration with η_acc ≳ 3/4 and traverses a dense low-ionization shell from an old supernova remnant in the pressure-driven snowplow regime.

  4. Testing the nature of dark compact objects: a status report

    gr-qc 2019-04 accept novelty 2.0

    Current and future observations can test whether dark compact objects are Kerr black holes or exotic alternatives, with null results strengthening the black hole paradigm.
