We report here the first polarimetric measurements of the pulsars in the J0737-3039 binary neutron star system using the Green Bank Telescope. The data suggest that the primary star (pulsar A) has a wide hollow cone of emission, which is an expected characteristic of the relatively open magnetosphere given its short spin period, and that pulsar A has a small angle between its spin and magnetic dipole axes, 4° ± 3°. This geometry suggests that pulsar A's wind pressure on pulsar B's magnetosphere… Expand
Magnetospheric interactions and emission properties in the double pulsar system
Abstract Our ability to observe both pulsars in the double-pulsar system, PSR J0737–3039A/B, combined with its short binary period and almost edge-on orbit, provides an unique opportunity to studyExpand
MAGNETOSPHERIC ECLIPSES IN THE DOUBLE PULSAR SYSTEM PSR J0737-3039
In the binary radio pulsar system PSR J0737-3039, the faster pulsar, A, is eclipsed once per orbit. A clear modulation of these eclipses at the 2.77 s period of pulsar B has recently been discovered.Expand
The Double Pulsar: Evidence for Neutron Star Formation without an Iron Core-collapse Supernova
The double pulsar system PSR J0737–3039A/B is a double neutron star binary, with a 2.4 hr orbital period, which has allowed measurement of relativistic orbital perturbations to high precision. TheExpand
Effects of Pulsar Rotation on Timing Measurements of the Double Pulsar System J0737–3039
We study the effect of pulsar rotation on the timing of binary pulsars, with particular emphasis on the double pulsar system J0737-3039. Special relativistic aberration due to the orbital motion of aExpand
PSR J0737-3039B: A PROBE OF RADIO PULSAR EMISSION HEIGHTS
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
The geometry of the double-pulsar system J0737–3039 from systematic intensity variations
TLDR
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.

Pulsar Kicks and Spin Tilts in the Close Double Neutron Stars PSR J0737–3039, PSR B1534+12, and PSR B1913+16
In view of the recent measurement of the scintillation velocity for PSR J0737-3039, we examine the complete set of constraints imposed on the pulsar B natal kicks (magnitude and orientation) andExpand
LONG-TERM STUDY OF THE DOUBLE PULSAR J0737–3039 WITH XMM-NEWTON: PULSAR TIMING
The relativistic double neutron star binary PSR J0737-3039 shows clear evidence of orbital phase-dependent wind-companion interaction, both in radio and X-rays. In this paper we present the resultsExpand
Studies of the Relativistic Binary Pulsar PSR B1534+12. II. Origin and Evolution
We have recently measured the angle between the spin and orbital angular momenta of PSR B1534+12 to be either 25° ± 4° or 155° ± 4°. This misalignment was almost certainly caused by an asymmetry inExpand

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).
