Short Gamma Ray Bursts as possible electromagnetic counterpart of coalescing binary systems [PDF]

open access: yes, 2010
Coalescing binary systems, consisting of two collapsed objects, are among the most promising sources of high frequency gravitational waves signals detectable, in principle, by ground-based interferometers.

Hyperon-Mixed Neutron Star Matter and Neutron Stars [PDF]

open access: yesProgress of Theoretical Physics, 2002
Effective Σ − n and Σ − Σ − interactions are derived fromthe G-matrix calculations for {n+Σ − } matter and employed in the investigation of hyperon mixing in neutron star matter. The threshold densities ρt(Y ) at which hyperons start to appear are between 2ρ0 and 3ρ0 (where ρ0 is the normal nuclear density) for both Λ and Σ − , and their fractions ...

Symmetry energy constraints from GW170817 and laboratory experiments

open access: yesPhysics Letters B, 2019
The LIGO-Virgo collaboration detection of the binary neutron-star merger event, GW170817, has expanded efforts to understand the Equation of State (EoS) of nuclear matter.

The influence of the enhanced vector meson sector on the properties of the matter of neutron stars. [PDF]

open access: yesPLoS ONE, 2014
This paper gives an overview of the model of a neutron star with non-zero strangeness constructed within the framework of the nonlinear realization of the chiral SU(3)L x SU(3)R symmetry.

Anisotropic pressure and hyperons in neutron stars

open access: yes, 2014
We study the effects of anisotropic pressure on properties of the neutron stars with hyperons inside its core within the framework of extended relativistic mean field. It is found that the main effects of anisotropic pressure on neutron star matter is to

PROPERTIES OF NEUTRON STARS [PDF]

open access: yesCompact 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 ...

Population of Merging Compact Binaries Inferred Using Gravitational Waves through GWTC-3

open access: yesPhysical Review X, 2023
We report on the population properties of compact binary mergers inferred from gravitational-wave observations of these systems during the first three LIGO-Virgo observing runs.

The most massive progenitors of neutron stars: CXO J164710.2-455216

open access: yes, 2008
The evolution leading to the formation of a neutron star in the very young Westerlund 1 star cluster is investigated. The turnoff mass has been estimated to be 35 Msun, indicating a cluster age ~ 3-5 Myr.
