Microlensing neutron stars [PDF]

open access: yesAstronomy & Astrophysics, 2002
We investigate the chances that neutron stars act as the lense in a gravitational microlensing event towards the galactic bulge or a spiral arm. The observation of neutron stars by means of gravitational microlensing would allow the estimation of neutron star masses independently of the property of being a pulsar in a binary system.

Holographic neutron stars [PDF]

open access: yesJournal 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 ...

Incommensurate Crystallization of Neutron Matter in Neutron Stars

open access: yesEast European Journal of Physics, 2020
The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One can only surmise on the properties of neutron stars from the spectroscopic data that may be available from time to ...

The Physics of Neutron Stars [PDF]

open access: yesScience, 2004
Neutron stars are some of the densest manifestations of massive objects in the universe. They are ideal astrophysical laboratories for testing theories of dense matter physics and provide connections among nuclear physics, particle physics, and astrophysics. Neutron stars may exhibit conditions and phenomena not observed elsewhere, such as

Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network [PDF]

open access: yesPublications Astronomical Society of Australia, 2020
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influenced by the presence of tides, which depend on the neutron star equation of

GW170817: Measurements of Neutron Star Radii and Equation of State. [PDF]

open access: yesPhysical Review Letters, 2018
On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system.

Initial data for black hole-neutron star binaries, with rotating stars [PDF]

open access: yes, 2016
The coalescence of a neutron star with a black hole is a primary science target of ground-based gravitational wave detectors. Constraining or measuring the neutron star spin directly from gravitational wave observations requires knowledge of the ...

Multimessenger constraints on the neutron-star equation of state and the Hubble constant

open access: yesScience, 2020
A combined multimessenger analysis Neutron stars are stellar remnants with densities greater than that of an atomic nucleus. The properties of matter under such extreme conditions are poorly understood and inaccessible to terrestrial laboratories ...

Nonparametric constraints on neutron star matter with existing and upcoming gravitational wave and pulsar observations [PDF]

open access: yesPhysical Review D, 2020
Observations of neutron stars, whether in binaries or in isolation, provide information about the internal structure of the most extreme material objects in the Universe.
