Mergers of neutron stars (NS + NS) or neutron stars and stellar-mass black holes (NS + BH) eject a small fraction of matter with a subrelativistic velocity. Upon rapid decompression, nuclear-density medium condenses into neutron-rich nuclei, most of them radioactive. Radioactivity provides a long-term heat source for the expanding envelope. A brief transient has a peak luminosity in the supernova range, and the bulk of radiation in the UV-optical domain. We present a very crude model of the… 


We study dynamical capture binary black hole–neutron star (BH–NS) mergers focusing on the effects of the neutron star spin. These events may arise in dense stellar regions, such as globular clusters,

Studying newborn neutron stars by the transient emission after stellar collapses and compact binary mergers

The formation of neutron stars (NSs), both from collapses of massive stars and mergers of compact objects, can be usually indicated by bright transients emitted from explosively-ejected material. In

Optical emission from a kilonova following a gravitational-wave-detected neutron-star merger

Optical to near-infrared observations of a transient coincident with the detection of the gravitational-wave signature of a binary neutron-star merger and with a low-luminosity short-duration γ-ray burst are reported.

r-Process Nucleosynthesis from Compact Binary Mergers

The merger of two neutron stars or of a neutron star and a black hole often result in the ejection of a few percents of a solar mass of matter expanding at high speed in space. Being matter coming

Neutron Star Mergers and Nucleosynthesis of Heavy Elements

The existence of neutron star mergers has been supported since the discovery of the binary pulsar and the observation of its orbital energy loss, consistent with General Relativity. They are

The Location and Environments of Neutron Star Mergers in an Evolving Universe

The simultaneous detection of gravitational and electromagnetic waves from a binary neutron star merger has both solidified the link between neutron star mergers and short-duration gamma-ray bursts

Binary Neutron Star Mergers: Mass Ejection, Electromagnetic Counterparts, and Nucleosynthesis

We present a systematic numerical relativity study of the mass ejection and the associated electromagnetic transients and nucleosynthesis from binary neutron star (NS) mergers. We find that a few

Low mass binary neutron star mergers : gravitational waves and neutrino emission

Neutron star mergers are among the most promising sources of gravitational waves for advanced ground-based detectors. These mergers are also expected to power bright electromagnetic signals, in the

Detectable radio flares following gravitational waves from mergers of binary neutron stars

Results of calculations are presented showing that the interaction of mildly relativistic outflows with the surrounding medium produces radio flares with peak emission at 1.4 gigahertz that persist at detectable (submillijansky) levels for weeks, out to a redshift of 0.1.

υ-driven winds from the remnant of binary neutron star mergers

We present a 3D hydrodynamic study of the neutrino-driven winds that emerge from the remnant of a neutron star merger, represented by a thick accretion disc orbiting around a massive neutron star.



Coalescing neutron stars as possible gamma-ray burst sources

We have simulated a variety of models, in order to shed light on the accessible physical conditions during the mergers, on the amount of matter dynamically ejected during the merging, on the

The tidal disruption of neutron stars by black holes in close binaries.

The formation of close, doubly compact binary systems from close massive binaries is considered. Massive X-ray binaries are shown to be possible progenitors of these systems. The recent observation

On the galactic and cosmic merger rate of double neutron stars

Previous calculations of the merging rate of double neutron star systems similar to the Hulse-Taylor binary pulsar B1913 + 16 have assumed lifetimes based on the sum of the radio pulsar spin-down age

The Rate of Neutron Star Binary Mergers in the Universe: Minimal Predictions for Gravity Wave Detectors

Of the many sources which gravitational wave observatories might see, merging neutron star binaries are the most predictable. Their waveforms at the observable frequencies are easy to calculate. And

Neutron Star and Black Hole Binaries in the Galaxy

We present a statistical analysis of the number and birthrate of double neutron star (NS-NS) binaries. We estimate that there are ∼10 4.5 z 0 such systems in the Galaxy, with a birthrate ∼10 −5 z 0

Gamma-ray bursters at cosmological distances

It is proposed that some, perhaps most, gamma-ray bursters are at cosmological distances, like quasars, with a redshift of about 1 or 2. This proposition requires a release of supernova-like energy

An X-ray pulsar with a superstrong magnetic field in the soft γ-ray repeater SGR1806 − 20

Soft γ-ray repeaters (SGRs) emit multiple, brief (∼0.1-s), intense outbursts of low-energy γ-rays. They are extremely rare—three are known in our Galaxy and one in the Large Magellanic Cloud. Two

Are Gamma-Ray Bursts in Star-Forming Regions?

The optical afterglow of the gamma-ray burst GRB 970508 (z=0.835) was a few hundred times more luminous than any supernova. Therefore, the name "hypernova" is proposed for the whole GRB/afterglow

LIGO: the Laser Interferometer Gravitational-Wave Observatory

The goal of the Laser Interferometric Gravitational-Wave Observatory (LIGO) is to detect and study gravitational waves (GWs) of astrophysical origin. Direct detection of GWs holds the promise of
