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.

Detecting supersymmetric Q-balls with neutron stars [PDF]
, 1998 Supersymmetric Q-balls trapped in neutron stars or white dwarfs may cause the stars to explode. Trapping of Q-balls in neutron stars is shown to be less likely, but trapping in neutron star progenitors more likely than hitherto assumed, making neutron ...

Statistical theory of thermal evolution of neutron stars [PDF]
, 2015 Thermal evolution of neutron stars is known to depend on the properties of superdense matter in neutron star cores. We suggest a statistical analysis of isolated cooling middle-aged neutron stars and old transiently accreting quasi-stationary neutron ...

Detectability of Continuous Gravitational Waves from Magnetically Deformed Neutron Stars
Galaxies, 2021 Neutron stars are known to contain extremely powerful magnetic fields. Their effect is to deform the shape of the star, leading to the potential emission of continuous gravitational waves.

How to identify a Strange Star [PDF]
, 1998 Contrary to young neutron stars, young strange stars are not subject to the r-mode instability which slows rapidly rotating, hot neutron stars to rotation periods near 10 ms via gravitational wave emission.

Quark Deconfinement in Rotating Neutron Stars
Universe, 2017 In this paper, we use a three flavor non-local Nambu–Jona-Lasinio (NJL) model, an improved effective model of Quantum Chromodynamics (QCD) at low energies, to investigate the existence of deconfined quarks in the cores of neutron stars.

Nucleonic Direct Urca Processes and Cooling of the Massive Neutron Star by Antikaon Condensations
Advances in Astronomy, 2020 Nucleonic direct Urca processes and cooling of the massive neutron stars are studied by considering antikaon condensations. Calculations are performed in the relativistic mean field and isothermal interior approximations.

Rapidly rotating neutron stars in $$f(R,T)=R+2 \lambda T$$ f ( R , T ) = R + 2 λ T gravity
European Physical Journal C: Particles and Fields, 2023 In this work, we study the influence of f(R, T) gravity on rapidly rotating neutron stars. First we discuss the main aspects of this modified theory of gravity where the gravitational Lagrangian is an arbitrary function of the Ricci scalar R and of the ...

Neutron Stars in the Symmetron Model
Universe, 2021 Screening mechanisms are often deployed by dark energy models to conceal the effects of their new degrees of freedom from the scrutiny of terrestrial and solar system experiments.
