Gravitational radiation and the binary pulsar [PDF]

open access: yesNature, 1982
Nature Vol. 297 3 June 1982 357 NEWS AND VIEWS Tq Gravitational radiation and the binary pulsar GRAVITATIONAL radiation not only exists, but it is apparently also doing exactly what general relativity says it ought to, at least in the binary pulsar PSRl9l3 + 16. This is the conclusion drawn by J .H. Taylor and J .M.

The Effect of Irradiation on the Spin of Millisecond Pulsars

open access: yesThe Astrophysical Journal Letters, 2023
A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.

2S 1553-542: a Be/X-ray binary pulsar on the far side of the Galaxy [PDF]

open access: yes, 2016
We report the results of a comprehensive analysis of X-ray (Chandra and Swift observatories), optical (Southern African Large Telescope, SALT) and near-infrared (the VVV survey) observations of the Be/X-ray binary pulsar 2S1553-542.

Pulsar emission amplified and resolved by plasma lensing in an eclipsing binary [PDF]

open access: yesNature, 2018
Radio pulsars scintillate because their emission travels through the ionized interstellar medium along multiple paths, which interfere with each other.

A timing formula for main-sequence star binary pulsars [PDF]

open access: yes, 1997
In binary radio pulsars with a main-sequence star companion, the spin-induced quadrupole moment of the companion gives rise to a precession of the binary orbit.

A Dense Companion to the Short-period Millisecond Pulsar Binary PSR J0636+5128 [PDF]

open access: yesAstrophysical Journal, 2018
PSR J0636+5128 is a millisecond pulsar in one of the most compact pulsar binaries known, with a 96 minute orbital period. The pulsar mass function suggests a very low mass companion, similar to that seen in so-called “black widow” binaries.

Bits Missing: Finding Exotic Pulsars Using bfloat16 on NVIDIA GPUs

open access: yesThe Astrophysical Journal Supplement Series, 2023
The Fourier domain acceleration search (FDAS) is an effective technique for detecting faint binary pulsars in large radio astronomy data sets. This paper quantifies the sensitivity impact of reducing numerical precision in the graphics processing unit ...

Tensor-scalar gravity and binary-pulsar experiments [PDF]

open access: yes, 1996
Some recently discovered nonperturbative strong-field effects in tensor-scalar theories of gravitation are interpreted as a scalar analog of ferromagnetism: "spontaneous scalarization".

Looking for Light Pseudoscalar Bosons in the Binary Pulsar System J0737-3039 [PDF]

open access: yes, 2005
We present numerical calculations of the photon-light-pseudoscalar-boson conversion in the recently discovered binary pulsar system J0737-3039. Light pseudoscalar bosons (LPBs) oscillate into photons in the presence of strong magnetic fields.

Strong-Field Gravity Tests with the Double Pulsar

open access: yesPhysical Review X, 2021
Continued timing observations of the double pulsar PSR J0737–3039A/B, which consists of two active radio pulsars (A and B) that orbit each other with a period of 2.45 h in a mildly eccentric (e=0.088) binary system, have led to large improvements in the ...
