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 the pulsars appears to be old and recycled with a spin period of only 22 ms. Its companion is younger and rotating slower with a period of 2.8 s, confirming the long‐proposed recycling theory for millisecond pulsars. The system provides an exciting opportunity to study the workings of pulsar magnetospheres…

Tests of General Relativity from Timing the Double Pulsar
By measuring relativistic corrections to the Keplerian description of the orbital motion, it is found that the “post-Keplerian” parameter s agrees with the value predicted by general relativity within an uncertainty of 0.05%, the most precise test yet obtained.
General Relativity support from the double pulsar
After the final publication of the Theory of General Relativity by Albert Einstein in 1916, experimental confirmation rested on three astronomical tests. These were the amount of bending of starlight
Prospects of constraining the dense matter equation of state from timing analysis of pulsars in double neutron star binaries
Lense-Thirring effect from spinning neutron stars in double neutron star binaries contribute to the periastron advance of the orbit. This extra term involves the moment of inertia of the neutron
The orthometric parametrization of the Shapiro delay and an improved test of general relativity with binary pulsars
In this paper, we express the relativistic propagational delay of light in the space-time of a binary system (commonly known as the 'Shapiro delay') as a sum of harmonics of the orbital period of the

Tempo2 is a new software package for the analysis of pulsar pulse times of arrival. In this paper we describe in detail the timing model used by tempo2, and discuss limitations on the attainable
Model-independent comparisons of pulsar timings to scalar-tensor gravity
Observations of pulsar timing provide strong constraints on scalar–tensor theories of gravity, but these constraints are traditionally quoted as limits on the microscopic parameters (like the

We propose to locate transponders and atomic clocks in at least three of the Lagrange points of the Sun-Earth pair, with the aim of exploiting the time of flight asymmetry between electromagnetic
A new well behaved class of charge analogue of Adler’s relativistic exact solution
The paper presents a new class of parametric interior solutions of Einstein–Maxwell field equations in general relativity for a static spherically symmetric distribution of a charged perfect fluid


The geometry of the double-pulsar system J0737–3039 from systematic intensity variations
A geometrical model of the PSR J0737–3039 system is reported that simultaneously explains the intensity variations of B and provides constraints on the spin axis orientation and emission geometry of A and predicts that A's pulse profile will evolve considerably over the next several years owing to geodetic precession.

Measurement of gravitational spin-orbit coupling in a binary-pulsar system.
These observations fix the system geometry, including the misalignment between the spin and orbital angular momenta, and yield a measurement of the precession time scale consistent with the predictions of general relativity.
