Microlensing neutron stars [PDF]
Astronomy & Astrophysics, 2002 We investigate the chances that neutron stars act as the lense in a gravitational microlensing event towards the galactic bulge or a spiral arm. The observation of neutron stars by means of gravitational microlensing would allow the estimation of neutron star masses independently of the property of being a pulsar in a binary system.

Neutron Stars and the Nuclear Matter Equation of State
, 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.

Evidence for quark-matter cores in massive neutron stars [PDF]
Nature Physics, 2019 The theory governing the strong nuclear force—quantum chromodynamics—predicts that at sufficiently high energy densities, hadronic nuclear matter undergoes a deconfinement transition to a new phase of quarks and gluons1.

Improved treatment of dark matter capture in neutron stars [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Neutron stars provide a cosmic laboratory to study the nature of dark matter particles and their interactions. Dark matter can be captured by neutron stars via scattering, where kinetic energy is transferred to the star.

Holographic neutron stars [PDF]
Journal of High Energy Physics, 2010 We construct in the context of the AdS/CFT correspondence degenerate composite operators in the conformal field theory that are holographically dual to degenerate stars in anti de Sitter space. We calculate the effect of the gravitational back-reaction using the Tolman-Oppenheimer-Volkoff equations, and determine the "Chandrasekhar limit" beyond which ...

On the Maximum Mass of Neutron Stars and GW190814 [PDF]
Astrophysical Journal, 2020 Motivated by the recent discovery of a compact object with mass in the range 2.5–2.67 M ⊙ in the binary merger GW190814, we revisit the question of the maximum mass of neutron stars (NSs).

Hyperon-Mixed Neutron Star Matter and Neutron Stars [PDF]
Progress of Theoretical Physics, 2002 Effective Σ − n and Σ − Σ − interactions are derived fromthe G-matrix calculations for {n+Σ − } matter and employed in the investigation of hyperon mixing in neutron star matter. The threshold densities ρt(Y ) at which hyperons start to appear are between 2ρ0 and 3ρ0 (where ρ0 is the normal nuclear density) for both Λ and Σ − , and their fractions ...

Hyperon–nucleon three-body forces and strangeness in neutron stars [PDF]
European Physical Journal A, 2020 Three-body forces acting on a $$\varLambda $$ Λ hyperon in a nuclear medium are investigated, with special focus on the so-called hyperon puzzle in neutron stars.
