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.

PSR J1909-3744, a Binary Millisecond Pulsar with a Very Small Duty Cycle

, 2003
We report the discovery of PSR J1909-3744, a 2.95 millisecond pulsar in a nearly circular 1.53 day orbit. Its narrow pulse width of 43 microseconds allows pulse arrival times to be determined with great accuracy.

On the Number of Confirmed Pulsar Planets: The Rule of Six

The Astrophysical Journal
Since the first definitive exoplanet detection, the three planets around millisecond radio pulsar PSR B1257+12, few more pulsar planets (PPs) have been reported.

Pulsar Based Alternative Timing Source for Grid Synchronization and Operation

IEEE Access, 2020
The need for timing sources that are alternatives to GPS has been under consideration for years. The reliance of power systems instrumentation and control systems on GPS timing serves as the basis for the study reported in this paper.

COBIPULSE: A Systematic Search for Compact Binary Millisecond Pulsars

The Astrophysical Journal
We report here the results obtained from a systematic optical photometric survey aimed at finding new compact binary millisecond pulsars (also known as “spiders”): the COmpact BInary PULsar SEarch. We acquired multiband optical images over 1 yr around 33

The Discovery of Three Pulsars in the Globular Cluster M15 with FAST

The Astrophysical Journal Letters
We present the discovery of three pulsars in the globular cluster (GC) M15 (NGC 7078) by the Five-hundred-meter Aperture Spherical Radio Telescope. PSR J2129+1210J (M15J) is a millisecond pulsar with a spin period of 11.84 ms and a dispersion measure of ...

Millisecond Pulsar Surveys [PDF]

Symposium - International Astronomical Union, 1987
In 1982 a new class of pulsars was defined by the discovery of a star with a millisecond rotation period, 1.6 ms. In the past 3.5 years two additional pulsars with millisecond periods have been discovered. The rapid spin of these pulsars is attributed to mass transfer in a low-mass binary progenitor system.
