The clocklike properties of pulsars moving in the gravitational fields of their unseen neutron-star companions have allowed unique tests of general relativity and provided evidence for gravitational radiation. We report here the detection of the 2.8-second pulsar J0737–3039B as the companion to the 23-millisecond pulsar J0737–3039A in a highly relativistic double neutron star system, allowing unprecedented tests of fundamental gravitational physics. We observed a short eclipse of J0737–3039A by… 

The double pulsar system: a unique laboratory for gravity

The PSR J0737–3039 is a double neutron star system in which both stars are detectable as active radio pulsars. The pair, consisting of an old, mildly recycled 23-ms pulsar and a young 2.8-s pulsar,


The double pulsar system J0737 – 3039 – a 22.7 ms pulsar in a compact 2.4 hr orbit about a 2.7 s pulsar was one of the long-awaited "holy grails" of pulsar astronomy. After only two years of timing,

Double Pulsar: A magnetopause in the double-pulsar binary system

One of the holy grails of pulsar astronomy was realized last year with the discovery of a double neutron-star binary system in which both stars are visible as radio pulsars. The stars in this highly

Probing fundamental physics with pulsars

Abstract Pulsars provide a wealth of information about General Relativity, the equation of state of superdense matter, relativistic particle acceleration in high magnetic fields, the Galaxy's

The double pulsar system J0737-3039

Recycled binary pulsars—a most precise laboratory of fundamental physics

We discuss here the problems connected with radio pulsars in close binary systems, which have an anomalously small magnetic field and rotate very rapidly. The first discovered Hulse–Taylor binary

Rapidly Rising Optical Transients from the Birth of Binary Neutron Stars

We study optical counterparts of a new-born pulsar in a double neutron star system like PSR J0737-3039A/B. This system is believed to have ejected a small amount of mass of  ( 0.1 M ⊙ ) at the

Magnetospheric Eclipses in the Double-Pulsar System PSR J0737–3039

We argue that eclipses of radio emission from the millisecond pulsar A in the double-pulsar system PSR J0737-3039 are due to synchrotron absorption by plasma in the closed field line region of the


In this work, we calculate the moment of inertia of the pulsar of the binary system J0737-3039A in the framework of Einstein's gravitational theory combined with a relativistic field theoretical

A detailed account of the parametrized post-Keplerian'' (PPK) formalism, a general phenomenological framework designed to extract the maximum possible information from pulsar timing and pulse-structure data, and how it can be combined with the predictions of a rather generic class of tensor biscalar theories to bring together tests based on observations of several different pulsars.

In addition to being fascinating objects to study in their own right, pulsars are exquisite tools for probing a variety of issues in basic physics. Recycled pulsars, thought to have been spun up in

Self-Consistency of Relativistic Observables with General Relativity in the White Dwarf-Neutron Star Binary PSR J1141–6545

Here we report timing measurements of the relativistic binary PSR J1141-6545 that constrain the component masses and demonstrate that the orbital period derivative b = (-4 ± 1) × 10-13 is consistent

Studies of the Relativistic Binary Pulsar PSR B1534+12. I. Timing Analysis

We have continued our long-term study of the double neutron star binary pulsar PSR B1534+12, using new instrumentation to make very high precision measurements at the Arecibo Observatory. We have

Does mass accretion lead to field decay in neutron stars?

WHETHER or not neutron-star magnetic fields decay is a matter of current debate. The recent observation1,2 of cyclotron lines from γ-ray-burst sources, thought to be relatively old neutron stars,

Evidence for geodetic spin precession in the binary pulsar 1913+16

Six years of careful observations have revealed a gradual secular evolution in the pulse profile of binary pulsar PSR 1913 + 16. At frequencies near 1400 MHz, the flux density in the first component

Higher-order relativistic periastron advances and binary pulsars

SummaryThe contributions to the periastron advance of a system of two condensed bodies coming from relativistic dynamical effects of order higher than the usual first post-Newtonian (1PN) equations

Pulsar distances and the galactic distribution of free electrons

We describe a quantitative model for the distribution of free electrons in the Galaxy, with particular emphasis on its utility for estimating pulsar distances from dispersion measures. Contrary to

Determination of the Geometry of the PSR B1913+16 System by Geodetic Precession

New observations of the binary pulsar B1913+16 are presented. Since 1978 the leading component of the pulse profile has weakened dramatically by about 40%. For the first time, a decrease in component

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
