Recent three-dimensional, high-resolution simulations of neutron star coalescences are analysed to assess whether short gamma-ray bursts (GRBs) could originate from such encounters. The two most popular modes of energy extraction - namely the annihilation of and magnetohydrodynamic processes - are explored in order to investigate their viability in launching GRBs. We find that annihilation can provide the necessary stresses to drive a highly relativistic expansion. However, unless the outflow… 
The Properties of Short gamma-ray burst Jets Triggered by neutron star mergers
The most popular model for short gamma-ray bursts (sGRBs) involves the coalescence of binary neutron stars. Because the progenitor is actually hidden from view, we must consider under which
The missing link: Merging neutron stars naturally produce jet-like structures and can power short gamma-ray bursts
Short Gamma-Ray Bursts (SGRBs) are among the most luminous explosions in the universe, releasing in less than one second the energy emitted by our Galaxy over one year. Despite decades of
Relativistic outflows from remnants of compact object mergers and their viability for short gamma-ray bursts
We present the first general relativistic hydrodynamic models of the launch and evolution of relativistic jets and winds, driven by thermal energy deposition, possibly due to neutrino-antineutrino
On the Conditions for Neutron-rich Gamma-Ray Burst Outflows
We calculate the structure and neutron content of neutrino-heated magnetohydrodynamic winds driven from the surface of newly formed magnetars (protomagnetars) and from the midplane of hyperaccreting
On the Central Engine of Short Gamma-Ray Bursts
We assess the ability of neutron star binary coalescence to produce short gamma-ray bursts (GRBs). We find that the neutrino annihilation above the merged remnant will drive bipolar, relativistic
Torus formation in neutron star mergers and well-localized short gamma-ray bursts
Merging neutron stars (NSs) are hot candidates for the still enigmatic sources of short gamma-ray bursts (GRBs). If the central engines of the huge energy release are accreting relic black holes
Zhang (2013) proposed a type of GRB-less X-ray transient associated with double neutron star (NS-NS) mergers under the conjecture of a rapidly-spinning magnetar merger product with the line of sight
Neutrino pair annihilation above merger remnants: implications of a long-lived massive neutron star
Binary neutron star mergers are plausible progenitor candidates for short gamma-ray bursts (GRBs); however, a detailed explanation of their central engine is still lacking. The annihilation of
The physics of gamma-ray bursts & relativistic jets
Abstract We provide a comprehensive review of major developments in our understanding of gamma-ray bursts, with particular focus on the discoveries made within the last fifteen years when their true
Neutrino-driven winds from neutron star merger remnants
We present a detailed, three-dimensional hydrodynamic study of the neutrino-driven winds that emerge from the remnant of a neutron star merger. Our simulations are performed with the Newtonian,


Jets, winds and bursts from coalescing neutron stars
Recent high-resolution calculations of neutron star coalescences are used to investigate whether ν ¯ ν annihilation can provide sufficient energy to power gamma-ray bursts, especially those belonging
Gamma-ray bursts as collimated jets from neutron star/black hole mergers
THE distribution of more than 150 γ-ray bursts detected by the BATSE experiment is isotropic on the sky but radially non-uniform1,2. This raises the possibility that bursts are cosmological (at z≲l)
Gamma-ray bursts as the death throes of massive binary stars
We propose that gamma-ray bursts are created in the mergers of double neutron star binaries and black hole neutron star binaries at cosmological distances. Two different processes provide the
Winds from massive stars: implications for the afterglows of γ‐ray bursts
Recent observations suggest that long-duration γ-ray bursts (GRBs) and their afterglows are produced by highly relativistic jets emitted in core-collapse explosions. The pre-explosive ambient medium
Collapsars: Gamma-ray bursts and explosions in 'failed supernovae'
Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα 10 M☉, in which iron-core collapse does not produce a successful outgoing
Formation Rates of Black Hole Accretion Disk Gamma-Ray Bursts
The cosmological origin of at least an appreciable fraction of classical gamma-ray bursts (GRBs) is now supported by redshift measurements for a half-dozen faint host galaxies. Still, the nature of
On the diversity of short gamma‐ray bursts
Hydrodynamical simulations of the last inspiral stages and the final coalescence of a double neutron star system are used to investigate the power of the neutrino-driven wind, the energy and momentum
High‐resolution calculations of merging neutron stars – II. Neutrino emission
The remnant resulting from the merger of two neutron stars produces neutrinos in copious amounts. In this paper we present the neutrino emission results obtained via Newtonian, high-resolution
Millisecond pulsars with extremely strong magnetic fields as a cosmological source of γ-ray bursts
THE spatial and luminosity distribution of γ-ray bursts as observed by the BATSE instrument on the Compton Gamma Ray Observatory1,2 provides support for the revival of the idea3,4 that the burst
Beam models for gamma-ray bursts sources: outflow structure, kinematics and emission mechanisms
Abstract The variety of γ-ray burst phenomenology could be largely attributable to differences in the opening angle of an isotropic outflow or to a standard type of event viewed from different
