High-energy emissions from neutron star mergers [PDF]

open access: yesEPJ Web of Conferences, 2019
In 2017, LIGO-Virgo collaborations reported detection of the first neutron star merger event, GW170817, which is accompanied by electromagnetic counterparts from radio to gamma rays.

On the minimum and maximum mass of neutron stars and the delayed collapse [PDF]

open access: yes, 2000
The minimum and maximum mass of protoneutron stars and neutron stars are investigated. The hot dense matter is described by relativistic (including hyperons) and non-relativistic equations of state.

Bayesian Model Selection of Unified Neutron Star EOSs in Multi-messenger Era

open access: yesYuanzineng kexue jishu, 2023
The equation of state (EoS) of neutron star matter plays a key role in both the structure and evolution of a neutron star. However, as lattice QCD faces significant difficulties in simulating dense matter, only effective models can be relied on to unveil

Low Mass Neutron Stars and the Equation of State of Dense Matter [PDF]

open access: yes, 2002
Neutron-star radii provide useful information on the equation of state of neutron rich matter. Particularly interesting is the density dependence of the equation of state (EOS).

Mirror neutron stars

open access: yesPhysical Review D, 2022
The fundamental nature of dark matter is entirely unknown. A compelling candidate is Twin Higgs mirror matter, invisible hidden-sector cousins of the Standard Model particles and forces. This predicts mirror neutron stars made entirely of mirror nuclear matter. We find their structure using realistic equations of state, robustly modified based on first-

GW170817 constraints analyzed with Gogny forces and momentum-dependent interactions

open access: yesPhysics Letters B, 2020
A set of equations of state obtained from finite-range Gogny forces and momentum-dependent interactions is used to investigate the recent observation of gravitational waves from the binary neutron star merger GW170817 event. For this set of interactions,

Universality and properties of neutron star type I critical collapses

open access: yes, 2011
We study the neutron star axisymmetric critical solution previously found in the numerical studies of neutron star mergers. Using neutron star-like initial data and performing similar merger simulations, we demonstrate that the solution is indeed a semi ...

Compactness of Neutron Stars

open access: yesPhysical Review Letters, 2015
Recent progress in the determination of both masses and radii of neutron stars is starting to place stringent constraints on the dense matter equation of state. In particular, new theoretical developments together with improved statistical tools seem to favor stellar radii that are significantly smaller than those predicted by models using purely ...

Sonoluminescence in neutron stars [PDF]

open access: yesPhysics Letters B, 1998
After a brief discussion of a possible relationship between the electroweak phase transition in highly compressed matter and gravitational collapse, we examine the speculative possibility that the electroweak phase transition might be contemporarily occurring in processes in neutron stars. We conjecture that adiabatic compression of neutron star matter
