A binary pulsar is a pulsar with a binary companion, often a white dwarf or neutron star. (In at least one case, the double pulsar PSR J0737-3039, the companion neutron star is another pulsar as well.) Binary pulsars are one of the few objects which allow physicists to test general relativity because of the strong gravitational
The Hulse–Taylor pulsar (known as PSR B1913+16, PSR J1915+1606 or PSR 1913+16) is a binary star system composed of a neutron star and a pulsar which orbit around their common center of mass. It is the first binary pulsar ever discovered.
PSR J0437−4715 is the first MSP to have its X-ray emission detected and studied in detail. [8] It is also the first of only two pulsars to have the full three-dimensional orientation of its orbit determined. [9] Optical observations indicate that the binary companion of PSR J0437-4715 is most likely a low-mass helium white dwarf. [2]

A circumbinary planet with a mass of 2.5 ± 1 Jupiter masses [76] orbits around PSR B1620-26, a binary star consisting of a pulsar and a white dwarf [1] in the globular cluster M4. [4] This planet may have been captured into the pulsar's orbit, a process which is particularly likely within the packed environment of a globular cluster, [ 15 ...
Highlights from the survey include the discoveries of the second most relativistic binary pulsar known, PSR J1906+0746, [2] and the first eccentric binary millisecond pulsar in the Galactic plane, PSR J1903+0327 [3] In addition, PALFA has produced the first pulsar discovery by volunteer computing, PSR J2007+2722, through the Einstein@Home ...
A pulsar–white dwarf system; e.g, PSR B1620−26. A pulsar–neutron star system, e.g, PSR B1913+16. A pulsar and a normal star; e.g, PSR J0045−7319, a system that is composed of a pulsar and main-sequence B star. Theoretically, a pulsar-black hole system is possible and would be of enormous scientific interest but no such system has yet ...
