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.

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.

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.

Dark matter admixed neutron stars [PDF]
Physical Review D, 2021 Neutron stars could contain a mixture of ordinary nuclear matter and dark matter, such that dark matter could influence observable properties of the star, such as its mass and radius.

Holographic modeling of nuclear matter and neutron stars [PDF]
The European Physical Journal C, 2021 I review holographic models for (dense and cold) nuclear matter, neutron stars, and their mergers. I start by a brief general discussion on current knowledge of cold QCD matter and neutron stars, and go on discussing various approaches to model cold ...

The Mass Distribution of Neutron Stars in Gravitational-wave Binaries [PDF]
Astrophysical Journal Letters, 2021 The discovery of two neutron star–black hole coalescences by LIGO and Virgo brings the total number of likely neutron stars observed in gravitational waves to six.

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.

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).

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.

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.
