Binary pulsar - Wikipedia
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.)
Hulse–Taylor pulsar - Wikipedia
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.
Binary Pulsars | COSMOS - Swinburne
Binary pulsars arise when a neutron star is formed in a binary system. If the system remains bound after the supernova explosion, there exists (for a short time) a normal pulsar in an eccentric orbit around a main sequence star (the secondary).
A binary pulsar in a 53-minute orbit | Nature
Jun 20, 2023 · Here we report radio observations of the binary millisecond pulsar PSR J1953+1844 (M71E) that show it to have an orbital period of 53.3 minutes and a companion with a mass of around 0.07 M⊙.
The past, present and future of pulsars | Nature Astronomy
Dec 1, 2017 · About 150 of the known pulsars are in binary systems — that is, they are twinned with another star. In several instances this other star is also a neutron star, and in one instance it is...
Pulsars in Binary Systems: Probing Binary Stellar Evolution ... - Science
A binary pulsar is defined here as a pulsar in orbit around a companion star of any type. Such a system has usually survived a violent and potentially disruptive supernova explosion that led to the formation of the neutron star.
The Astrophysics Spectator: Binary Pulsars and Millisecond Pulsars
Binary pulsars have two uses: they give us ancient neutron stars to study, and they provide a natural experimental apparatus for testing general relativity. The pulsar in a binary pulsar is quite different from the common isolated radio pulsar .
Pulsars were first discovered in 1967 by Antony Hewish and Jocelyn Bell at Cambridge University, work for which a Nobel Prize was awarded in 1974. At the time, they were engaged in a study of the rapid fluctuations of signals from astrophysical radio sources known as scintillations.

Nov 5, 2008 · We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have …
Binary Pulsars - Стэнфордский университет
Dec 10, 2007 · The first binary pulsar was discovered by Joseph Taylor and Russell Hulse in 1974 during a search for new pulsars at the Arecibo telescope. The pulsar is named PSR 1913+16, and is in a highly elliptical orbit around its companion neutron star with a period (or year) of around eight hours.
