Relativistic Binary Pulsars with Black Hole Companions [PDF]

The Astrophysical Journal, 2005
Binaries containing a stellar-mass black hole and a recycled radio pulsar have so far eluded detection. We present a focused investigation of the formation and evolution of these systems in the Galactic disk, highlighting the factors that limit their numbers and the reasons why they may be extremely rare.

A Radio Pulsar/X-ray Binary Link [PDF]

Science, 2009
From X-ray Binary to Pulsar Pulsars with millisecond rotational periods are thought to originate from neutron stars in low-mass x-ray binaries that had their spin frequencies increased by long-lasting mass transfer from their companion stars. Using data from a radio pulsar survey, Archibald

1974: the discovery of the first binary pulsar [PDF]

, 2015
The 1974 discovery, by Russell A. Hulse and Joseph H. Taylor, of the first binary pulsar PSR B1913+16, opened up new possibilities for the study of relativistic gravity.

Gravity Tests with Radio Pulsars

Universe, 2020
The discovery of the first binary pulsar in 1974 has opened up a completely new field of experimental gravity. In numerous important ways, pulsars have taken precision gravity tests quantitatively and qualitatively beyond the weak-field slow-motion ...

Radio pulsar binaries in globular clusters: their orbital eccentricities and stellar interactions

, 2009
High sensitivity searches of globular clusters (GC) for radio pulsars by improved pulsar search algorithms and sustained pulsar timing observations have so far yielded some 140 pulsars in more than two dozen GCs.

PSR J2150+3427: A Possible Double Neutron Star System

The Astrophysical Journal Letters, 2023
PSR J2150+3427 is a 0.654 s pulsar discovered by the Commensal Radio Astronomy FAST Survey. From the follow-up observations, we find that the pulsar is in a highly eccentric orbit ( e = 0.601) with an orbital period of 10.592 days and a projected ...

The origin of single radio pulsars

, 1999
By comparing relative rates of supernovae versus formation rates of single radio pulsars, recycled pulsars, binary pulsars and X-ray binaries we put strong limits on the progenitors of radio pulsars and on the requirement of an asymmetry in the supernova.

Millisecond Pulsars, their Evolution and Applications

, 2017
Millisecond pulsars (MSPs) are short-period pulsars that are distinguished from "normal" pulsars, not only by their short period, but also by their very small spin-down rates and high probability of being in a binary system.

Born to be recycled: A comprehensive population synthesis of the Galactic millisecond pulsars

Astronomy & Astrophysics
Context. Millisecond pulsars (MSPs) are the oldest and fastest pulsars known to date. The first MSP to be discovered was PSR B1937+21 in 1982. To explain how these pulsars could be formed, a new hypothesis was formulated: the recycling of pulsars, i.e ...
