Strongly interacting matter exhibits deconfined behavior in massive neutron stars [PDF]
Nat Commun, 2023 Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear matter melts into deconfined quark matter, liberating its constituent quarks and gluons.

Neutron-mirror neutron mixing and neutron stars [PDF]
European Physical Journal C: Particles and Fields, 2021 The oscillation of neutron n into mirror neutron $$n'$$ n ′ , its mass degenerate partner from dark mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part of mirror dark matter.

QCD equations of state and speed of sound in neutron stars [PDF]
AAPPS Bulletin, 2021 Neutron stars are cosmic laboratories to study dense matter in quantum chromodynamics (QCD). The observable mass-radius relations of neutron stars are determined by QCD equations of state and can reflect the properties of QCD phase transitions.

Neutron Stars and the Nuclear Matter Equation of State
Annual Review of Nuclear and Particle Science, 2021 Neutron stars provide a window into the properties of dense nuclear matter. Several recent observational and theoretical developments provide powerful constraints on their structure and internal composition.

Masses, Radii, and the Equation of State of Neutron Stars [PDF]
Annual Review of Astronomy and Astrophysics, 2016 We summarize our current knowledge of neutron-star masses and radii. Recent instrumentation and computational advances have resulted in a rapid increase in the discovery rate and precise timing of radio pulsars in binaries in the past few years, leading ...

Thermal luminosities of cooling neutron stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 Ages and thermal luminosities of neutron stars, inferred from observations, can be interpreted with the aid of the neutron star cooling theory to gain information on the properties of superdense matter in neutron-star interiors.

Tidal Deformabilities and Radii of Neutron Stars from the Observation of GW170817 [PDF]
Physical Review Letters, 2018 We use gravitational-wave observations of the binary neutron star merger GW170817 to explore the tidal deformabilities and radii of neutron stars.

Cooling of neutron stars with quark-hadron continuity [PDF]
EPJ Web of Conferences, 2022 Neutron stars are high-density objects formed by the gravitational collapse of massive stars, and the whole star can be likened to a giant nucleus. The interior of a neutron star is considered to contain exotic particles and states which do not appear in

On the Sound Speed in Neutron Stars [PDF]
Astrophysical Journal Letters, 2022 Determining the sound speed c s in compact stars is an important open question with numerous implications on the behavior of matter at large densities and hence on gravitational-wave emission from neutron stars.
