Black hole/pulsar binaries in the Galaxy [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2018
ABSTRACT We have performed population synthesis calculation on the formation of binaries containing a black hole (BH) and a neutron star (NS) in the Galactic disc. Some of important input parameters, especially for the treatment of common envelope evolution, are updated in the calculation.

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.

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 ...

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 ...

An Eccentric Binary Millisecond Pulsar in the Galactic Plane [PDF]

Science, 2008
Binary pulsar systems are superb probes of stellar and binary evolution and the physics of extreme environments. In a survey with the Arecibo telescope, we have found PSR J1903+0327, a radio pulsar with a rotational period of 2.15 milliseconds in a highly eccentric ( e = 0.44) 95-day orbit around a solar mass (

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 ...

Upper Limits on Pulsed Radio Emission from Unseen Compact Objects in Six Galactic Stellar Binaries

The Astrophysical Journal
We have conducted a search for radio pulsars in six Galactic stellar binary systems with unseen primary stars. All six systems have estimated primary masses in the range that could be consistent with neutron stars.

TeV astronomy of millisecond pulsars [PDF]

, 1991
This thesis is concerned with the detection of pulsed TeV γ-rays from millisecond pulsars. These stars appear to include some very efficient producers of high energy particles, but the mechanisms by which they produce TeV γ-rays are still a matter of ...

RELATIVISTIC SPIN-PRECESSION IN BINARY PULSARS [PDF]

The Twelfth Marcel Grossmann Meeting, 2012
After the first prediction to expect geodetic precession in binary pulsars in 1974, made immediately after the discovery of a pulsar with a companion, the effects of relativistic spin precession have now been detected in all binary systems where the magnitude of the precession rate is expected to be sufficiently high.
