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 ...

Multi-Wavelength Polarimetry of Isolated Neutron Stars
Galaxies, 2018 Isolated neutron stars are known to be endowed with extreme magnetic fields, whose maximum intensity ranges from 10 12 – 10 15 G, which permeates their magnetospheres. Their surrounding environment is also strongly magnetized, especially in

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.

Many Aspects of Magnetic Fields in Neutron Stars
Universe, 2018 In this work, we explore different aspects in which strong magnetic fields play a role in the composition, structure and evolution of neutron stars. More specifically, we discuss (i) how strong magnetic fields change the equation of state of dense matter,

Boson and neutron stars with increased density
Physics Letters B, 2020 We discuss boson stars and neutron stars, respectively, in a scalar-tensor gravity model with an explicitly time-dependent real scalar field. While the boson stars in our model – in contrast to the neutron stars – do not possess a hard core, we find that

Evolution of Neutron Star Magnetic Fields
Universe, 2021 Neutron stars are natural physical laboratories allowing us to study a plethora of phenomena in extreme conditions. In particular, these compact objects can have very strong magnetic fields with non-trivial origin and evolution.

What can neutron stars reveal about the equation of state of dense matter? [PDF]
EPJ Web of Conferences, 2020 Neutron stars are astrophysical objects of extremes, reaching the highest densities we can observe in the cosmos, and probing matter under conditions that cannot be recreated in terrestrial experiments.
