Discovery of three binary millisecond pulsars

The Astrophysical Journal, 1994
We report the discovery of three binary millisecond pulsars in circular orbits with low-mass companions from a continuing survey of the southern sky with the Parkes radio telescope. The three pulsars, PSR J0034-0534, PSR J1045-4509, and PSR J2145-0750 have pulse periods of 1.87, 7.47, and 16.05 ms and orbital periods of 1.6, 4.1, and 6.8 days ...

A Systematic Search for Redback and Black Widow Candidates Based on the 4FGL-DR3 Unassociated Sources and the Zwicky Transient Facility Data

The Astrophysical Journal
Spider pulsars represent a unique subclass of radio millisecond pulsars in binaries, and are further categorized into black widows and redbacks according to the mass of the low-mass companion.

Deciphering Profile Stability in Millisecond Pulsars: Timescales, Frequency Evolution, and Implications on Emission Mechanisms

The Astrophysical Journal
Pulse profile stability in millisecond pulsars (MSPs) is a key factor in achieving high-precision timing essential for detecting nanohertz gravitational waves with pulsar timing arrays (PTAs).

Pulse Profile Variability of PSR J1022+1001 in NANOGrav Data

The Astrophysical Journal
Pulse profile stability is a central assumption of standard pulsar timing methods. Thus, it is important for pulsar timing array experiments such as the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) to account for any pulse ...
