We apply the algorithm published by Liang et al. (2014) to describe the Double Pulsar system J0737$-$3039 and extract the sense of rotation of first born recycled pulsar PSR J0737$-$3039A. We find that this pulsar is rotating prograde in its orbit. This is the first direct measurement of the sense of rotation of a pulsar with respect to its orbit and a direct confirmation of the rotating lighthouse model for pulsars. This result confirms that the spin angular momentum vector is closely aligned… Expand
Understanding and improving the timing of PSR J0737−3039B
The double pulsar (PSR J0737-3039A/B) provides some of the most stringent tests of general relativity (GR) and its alternatives. The success of this system in tests of GR is largely due to theExpand
Constraining the dense matter equation-of-state with radio pulsars
Radio pulsars provide some of the most important constraints for our understanding of matter at supranuclear densities. So far, these constraints are mostly given by precision mass measurements ofExpand
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 neutronExpand


Testing the rotating lighthouse model with the double pulsar system PSR J0737-3039A/B
Each of the two pulsars in the double pulsar PSR J0737-3039A/B system exhibits not only the pulses emanating from itself, but also displays modulations near the pulse period of the other. Freire etExpand
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
We present the evolution of the radio emission from the 2.8 s pulsar of the double pulsar system PSR J0737- 3039A/B. We provide an update on the Burgay et al. analysis by describing the changes inExpand
In the double pulsar system PSR J0737–3039A/B, the strong wind produced by pulsar A distorts the magnetosphere of pulsar B. The influence of these distortions on the orbital-dependent emissionExpand
TOPICAL REVIEW: 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,Expand
A new technique for timing the double pulsar system
In 2004, McLaughlin et al. discovered a phenomenon in the radio emission of PSR J0737-3039B (B) that resembles drifting subpulses. The repeat rate of the subpulses is equal to the spin frequency ofExpand
The formation of the double pulsar PSR J0737−3039A/B
Recent timing observations of the double pulsar J0737−3039A/B have shown that its transverse velocity is extremely low, only 10 km s −1 , and nearly in the plane of the Galaxy. With this newExpand
A Double-Pulsar System: A Rare Laboratory for Relativistic Gravity and Plasma Physics

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. Expand
