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.

PROPERTIES OF NEUTRON STARS [PDF]
Compact Stars, 2004 I review attempts made to determine the properties of neutron stars. I focus on constraints on the maximum mass that a neutron star can have, and on attempts to measure neutron-star radii. So far, there appears to be only one neutron star for which there is strong evidence that its mass is above the canonical 1.4 Msun, viz., Vela X-1, for which a mass ...

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,

The Mass Distribution of Galactic Double Neutron Stars [PDF]
Astrophysical Journal, 2019 The conventional wisdom, dating back to 2012, is that the mass distribution of Galactic double neutron stars (DNSs) is well-fit by a Gaussian distribution with a mean of 1.33 M⊙ and a width of 0.09 M⊙.

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 ...

Capture of leptophilic dark matter in neutron stars [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 Dark matter particles will be captured in neutron stars if they undergo scattering interactions with nucleons or leptons. These collisions transfer the dark matter kinetic energy to the star, resulting in appreciable heating that is potentially ...

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.

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

Identification of strontium in the merger of two neutron stars [PDF]
Nature, 2019 Half of all of the elements in the Universe that are heavier than iron were created by rapid neutron capture. The theory underlying this astrophysical r-process was worked out six decades ago, and requires an enormous neutron flux to make the bulk of the

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 ...
