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 ...

The ultimate outcome of black hole - neutron star mergers [PDF]

open access: yes, 2004
We present a simple, semi--analytical description for the final stages of mergers of black hole (BH) -- neutron star (NS) systems. Such systems are of much interest as gravitational wave sources and gamma--ray burst progenitors.

Quasiequilibrium sequences of black-hole--neutron-star binaries in general relativity [PDF]

open access: yes, 2006
We construct quasiequilibrium sequences of black hole-neutron star binaries for arbitrary mass ratios by solving the constraint equations of general relativity in the conformal thin-sandwich decomposition.

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.

The evolution of low mass, close binary systems with a neutron star component: a detailed grid [PDF]

open access: yes, 2012
In close binary systems composed of a normal, donor star and an accreting neutron star, the amount of material received by the accreting component is, so far, a real intrigue.

A magnetically driven origin for the low luminosity GRB 170817A associated with GW170817

open access: yes, 2018
The gamma-ray burst GRB 170817A associated with GW170817 is subluminous and subenergetic compared with other typical short GRBs. It may be due to a relativistic jet viewed off-axis, or a structured jet, or cocoon emission. Giant flares from magnetars may

Time Evolution of Relativistic Force-Free Fields Connecting a Neutron Star and its Disk

open access: yes, 2005
We study the magnetic interaction between a neutron star and its disk by solving the time-dependent relativistic force-free equations. At the initial state, we assume that the dipole magnetic field of the neutron star connects the neutron star and its ...

Insights on Skyrme parameters from GW170817

open access: yes, 2019
The binary neutron-star merger event, GW170817, has cast a new light on nuclear physics research. Using a neutron-star model that includes a crust equation of state (EoS), we calculate the properties of a 1.4 solar-mass neutron star.

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 ...

The extended, relativistic hyperon star model [PDF]

open access: yes, 2002
In this paper an equation of state of neutron star matter which includes strange baryons in the framework of Zimanyi and Moszkowski (ZM) model has been obtained.
