Binary Pulsars: Observations and Implications [PDF]

Symposium - International Astronomical Union, 1987
The Galaxy contains a large number of neutron stars in gravitation-ally bound binary systems. Among the most fruitful of these to study have been the binary radio pulsars, of which seven are now known. Unlike the “accretion-powered” neutron stars located in mass-exchanging X-ray binary systems, the “rotation-powered” binary radio pulsars are found in ...

Algorithmic Pulsar Timer for Binaries

The Astrophysical Journal
Pulsar timing is a powerful tool that, by accounting for every rotation of a pulsar, precisely measures the spin frequency, spin frequency derivatives, astrometric position, binary parameters when applicable, properties of the interstellar medium, and ...

Discovering Pulsars in Compact Binaries with a Hidden Markov Model

The Astrophysical Journal
Discovering radio pulsars in compact binaries, whose orbital periods P _b satisfy P _b ≲ 1 day, is computationally challenging, because the time-dependent pulse frequency f _p ( t ) is strongly Doppler modulated by the binary motion.

Temporal Variations in Pulsar Spectropolarimetry: Findings from Millisecond Pulsar J2144–5237 Using Parkes UWL Receiver

The Astrophysical Journal
While the temporal variations of the spectropolarimetric nature of pulsars remain unexplored, this investigation offers significant potential for uncovering key insights into pulsar emission mechanisms, magnetic field geometry, and propagation effects ...

A 350 MHz Green Bank Telescope Survey of Unassociated Fermi LAT Sources: Discovery and Timing of 10 Millisecond Pulsars

The Astrophysical Journal
We have searched for radio pulsations toward 49 Fermi Large Area Telescope (LAT) 1FGL Catalog γ -ray sources using the Green Bank Telescope at 350 MHz. We detected 18 millisecond pulsars (MSPs) in blind searches of the data; 10 of these were discoveries ...
