Binary and Other Recycled Pulsars [PDF]

open access: yesSymposium - International Astronomical Union, 1992
Binary pulsars and others with weak fields and rapid rotation now number several dozen and appear to have been spun up by close binary mass transfer. Some are lineal descendents of X-ray binaries; others may result from accretion-induced collapse of binary white dwarfs or from captures, exchanges, and collisions in clusters. Seven accurate neutron star

Constraints on Undetected Long-period Binaries in the Known Pulsar Population

open access: yesThe Astrophysical Journal, 2023
Although neutron star–black hole binaries have been identified through mergers detected in gravitational waves, a pulsar–black hole binary has yet to be detected.

Binary gamma-ray pulsars

open access: yes, 2021
The first pulsar has been detected in 1967 as a seemingly pulsating radio source. Since then, more than 2800 pulsars have been discovered. Most of them also in radio. With the launch of the Fermi Gamma-ray Space Telescope in 2008, more than 250 gamma-ray

Binary Pulsars [PDF]

open access: yesSymposium - International Astronomical Union, 1981
There are now three radio frequency pulsars known to be in binary systems: PSRs 1913+16, 0820+02, and 0655+64. The first of these, discovered in 1974, moves in a tight, highly eccentric orbit with a period of approximately 7h 45m. Its companion has not yet been identified with certainty, but must be a compact object of mass comparable to that of the ...

On the Orbital Properties of Millisecond Pulsar Binaries [PDF]

open access: yesThe Astrophysical Journal, 2018
Abstract We report a detailed analysis of the orbital properties of a binary millisecond pulsar (MSP) with a white dwarf (WD) companion. Positive correlations between the orbital period P b and eccentricity ϵ are found in two classes of MSP binaries with a He WD and with a CO/ONeMg WD, though their trends are different.

Origin of the Binary Pulsar J0737-3039B

open access: yesPhysical Review Letters, 2005
Evolutionary scenarios suggest that the progenitor of the new binary pulsar J0737-3039B \cite{ref1,ref2} was a He-star with $M > 2.1-2.3~\Ms$ \cite{ref3,ref4}. We show that this case implies that the binary must have a large ($>120$ km/s) center of mass velocity.

SOME EVOLUTIONARY ASPECTS OF THE BINARY STELLAR SYSTEMS CONTAINING NEUTRON STAR

open access: yesOdessa Astronomical Publications, 2012
The obvious lack of the binary stellar systems that contain neutron stars (NS) is observed at present. Partly it is caused by the fact that it is very difficult to detect neutron star in a binary system if this relativistic component does not manifest ...

A Search for Gravitational Waves from Perturbed Black Hole Ringdowns in LIGO Data [PDF]

open access: yes, 2008
According to General Relativity a perturbed black hole will return to a stable configuration by the emission of gravitational radiation in a superposition of quasi-normal modes. Such a perturbation will occur due to the coalescence of a black hole binary,

Are many pulsars processed in binary systems? [PDF]

open access: yes, 1995
A detailed statistical analysis of pulsar current is presented. The conclusions reached are the following: (1) The birthrate of pulsars is about one in 75 ± 15 years. (2) There is evidence for injection of pulsars into the population of solitary pulsars.
