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.

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.

Constraints on physics of neutron stars from X-ray observations [PDF]
, 2013 I summarize some constraints on the physics of neutron stars arising from X-ray observations of the surfaces of neutron stars, focusing on using models of low-magnetic-field neutron star atmospheres to interpret their X-ray spectra.

Neutron stars in the laboratory [PDF]
International Journal of Modern Physics D, 2017 Neutron stars are astrophysical laboratories of many extremes of physics. Their rich phenomenology provides insights into the state and composition of matter at densities which cannot be reached in terrestrial experiments. Since the core of a mature neutron star is expected to be dominated by superfluid and superconducting components, observations ...

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 ...

The equilibrium configuration of rotating neutron stars [PDF]
Iranian Journal of Physics Research, 2022 Using the density-dependent equation of states to describe the matter of rotating neutron stars, we construct equilibrium configurations of rotating neutron stars. The interaction between baryons is described by exchanging the scalar and vector mesons in

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.

Neutron skins and neutron stars [PDF]
AIP Conference Proceedings, 2013 The neutron-skin thickness of heavy nuclei provides a fundamental link to the equation of state of neutron-rich matter, and hence to the properties of neutron stars. The Lead Radius Experiment ("PREX") at Jefferson Laboratory has recently provided the first model-independence evidence on the existence of a neutron-rich skin in 208Pb.

The Masses of Neutron Stars [PDF]
, 2016 We present in this article an overview of the problem of neutron star masses. After a brief appraisal of the methods employed to determine the masses of neutron stars in binary systems, the existing sample of measured masses is presented, with a highlight on some very well-determined cases.
