Two pulsars (PSR J0737–3039A and B) were recently discovered in highly relativistic orbits around one another. The system contains a rapidly rotating pulsar with a spin period of 22.7 ms and a slow companion with a spin period of 2.77 s, referred to here as ‘A’ and ‘B’, respectively. A unique property of the system is that the pulsed radio flux from B increases systematically by almost two orders of magnitude during two short portions of its orbit. Here we report a geometrical model of the… Expand

The Double Pulsar System J0737–3039: Modulation of the Radio Emission from B by Radiation from A
We have analyzed single pulses from PSR J0737-3039B, the 2.8 s pulsar in the recently discovered double pulsar system, using data taken with the Green Bank Telescope at 820 and 1400 MHz. We reportExpand
A Model for the flaring radio emission in the double pulsar system J0737-3039
The binary system J07373039AB includes two pulsars in a highly relativistic orbit. The pulsed radio flux from pulsar B brightens considerably during two portions of each orbit. This phenomenon cannotExpand
The mean pulse profile of PSR J0737-3039A
General relativity predicts that the spin axes of the pulsars in the double-pulsar system PSR J0737-3039A/B will precess rapidly, in general leading to a change in the observed pulse profiles. WeExpand
Strong-Field Tests of Gravity with the Double Pulsar
This first-ever double-pulsar system was discovered in 2003, consisting of two visible pulsars which orbit the common centre of mass in a slightly eccentric orbit in only 2.4 hours. One of theExpand
Orbital modulation of emission of the binary pulsar J0737-3039b
In the binary radio pulsar system J0737−3039, the slow pulsar B shows intense orbital modulations, with these being especially bright at two short orbital phases. We propose that these modulationsExpand
Long-term variations in the pulse emission from PSR J0737-3039B
Analysis of 20 months of observations at the Parkes radio telescope shows secular changes in the pulsed emission from J0737-3039B, the 2.77 s pulsar of the double-pulsar system. Pulse profiles areExpand
Effects of Gravitational Lensing in the Double Pulsar System J0737?3039
We investigate the effects of gravitational lensing in the binary pulsar system J0737-3039. Current measurement of the orbital inclination allows the millisecond pulsar (A) to pass very close (atExpand

The double pulsar system PSR J0737-3039A/B offers exceptional possibilities for detailed probes of the structure of the pulsar magnetosphere, pulsar winds and relativistic reconnection. WeExpand
The Double Pulsar
A new eaa in fundamental physics began with the discovery of pulsars 1967, the discovery of the first binary pulsar in 1974 and the first millisecond pulsar in 1982. Ever since, pulsars have beenExpand
XMM-Newton Observation of the Double Pulsar System J0737?3039
We report on a 50 ks XMM-Newton observation of the double pulsar system J0737-3039 performed in 2004 April. We present results of the spectral analysis of these data combined with the much shorterExpand

TLDR
This work reports the discovery of a 22-ms pulsar, PSR J0737–3039, which is a member of a highly relativistic double-neutron-star binary with an orbital period of 2.4 hours, which implies an order-of-magnitude increase in the predicted merger rate for double- NEUTron- star systems in the authors' Galaxy (and in the rest of the Universe).
