The merger of close binary systems containing two neutron stars should produce a burst of gravitational waves, as predicted by the theory of general relativity. A reliable estimate of the double-neutron-star merger rate in the Galaxy is crucial in order to predict whether current gravity wave detectors will be successful in detecting such bursts. Present estimates of this rate are rather low, because we know of only a few double-neutron-star binaries with merger times less than the age of the… 

Characterizing Astrophysical Binary Neutron Stars with Gravitational Waves

Merging binary neutron stars are thought to be formed predominantly via isolated binary evolution. In this standard formation scenario, the first-born neutron star goes through a recycling process


The discovery of two neutron stars with gravitational masses ≈ 2 M ⊙ ?> has placed a strong lower limit on the maximum mass of nonrotating neutron stars, and with it a strong constraint on the

Testing the Formation Scenarios of Binary Neutron Star Systems with Measurements of the Neutron Star Moment of Inertia

Two low-mass (M < 1.4 M⊙) neutron stars, J0737-3039B and the companion to J1756-2251, show strong evidence of being formed in an ultra-stripped supernova explosion (US-SN) with a ONeMg or Fe

The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/Virgo GW170817. VII. Properties of the Host Galaxy and Constraints on the Merger Timescale

We present the properties of NGC 4993, the host galaxy of GW170817, the first gravitational-wave (GW) event from the merger of a binary neutron star (BNS) system and the first with an electromagnetic

On August 17, 2017, less than two years after the direct detection of gravitational radiation from the merger of two ∼ 30 M ⊙ black holes, a binary neutron star merger was identified as the source of

On the Eccentricities and Merger Rates of Double Neutron Star Binaries and the Creation of “Double Supernovae”

We demonstrate that a natural consequence of an asymmetric kick imparted to neutron stars at birth is that the majority of double neutron star binaries should possess highly eccentric orbits. This

The Cosmic Coalescence Rates for Double Neutron Star Binaries

We report on the newly increased event rates due to the recent discovery of the highly relativistic binary pulsar J0737-3039. Using a rigorous statistical method, we present the calculations reported

The long and the short of it: modelling double neutron star and collapsar Galactic dynamics

Understanding the nature of galactic populations of double compact binaries (where both stars are a neutron star or black hole) has been a topic of interest for many years, particularly the

Einstein@Home discovery of a Double-Neutron Star Binary in the PALFA Survey

We report here the Einstein@Home discovery of PSR J1913+1102, a 27.3 ms pulsar found in data from the ongoing Arecibo PALFA pulsar survey. The pulsar is in a 4.95 hr double neutron star (DNS) system

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

The Coalescence Rate of Double Neutron Star Systems

We estimate the coalescence rate of close binaries with two neutron stars (NS) and discuss the prospects for the detection of NS-NS inspiral events by ground-based gravitational-wave observatories,

Neutron Star Mass Measurements. I. Radio Pulsars

There are now about 50 known radio pulsars in binary systems, including at least five in double neutron star binaries. In some cases, the stellar masses can be directly determined from measurements

The Probability Distribution Of Binary Pulsar Coalescence Rates. II. Neutron Star-White Dwarf Binaries

We consider the statistics of pulsar binaries with white dwarf companions (NS-WD). Using the statistical analysis method developed by Kim and coworkers, we calculate the Galactic coalescence rate of

Pulsar Spin Evolution, Kinematics, and the Birthrate of Neutron Star Binaries

From considerations of spin evolution and kinematics in the Galactic potential, we argue that the pulsars B1913+16, B1534+12, and B2127+11C may be younger than previously assumed, and we find that a

Determining the stellar masses in the binary system containing the pulsar PSR 1913 + 16 - Is the companion a helium main-sequence star

The stellar masses and the angle of inclination are determined for the system containing PSR 1913+16 in terms of the observable periastron advance and second-order relativistic effects, for the cases
