Component-dependent Periodic Emission Variations of PSR J1857+0943 Observed with FAST

The Astrophysical Journal
Single-pulse studies of millisecond pulsars provide an important way to probe the plasma processes responsible for their radio emission, but such studies remain rare because of the weak emission and short rotation periods of these objects. Using the high

Population synthesis of millisecond and submillisecond pulsars

, 1998
Known millisecond pulsars have periods longer than 1.558 ms. Recycled in binary systems, neutron stars can attain very short spin periods. In this Letter, we investigate the expected properties of the millisecond pulsar distribution by simulating ...

Follow-up Timing of 12 Pulsars Discovered in Commensal Radio Astronomy FAST Survey

The Astrophysical Journal
We present phase-connected timing ephemerides, polarization pulse profiles, and Faraday rotation measurements of 12 pulsars discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in the Commensal Radio Astronomy FAST Survey.

A FAST search for radio pulsations during the dormant state of the accreting millisecond pulsars IGR J00291+5934 and MAXI J1957+032

Astronomy & Astrophysics
Accreting millisecond pulsars (AMSPs) and transitional millisecond pulsars (tMSPs) are neutron star low-mass X-ray binaries that can evolve into recycled radio millisecond pulsars.

A Survey for Millisecond Pulsars

, 2007
We have searched 960 square degrees of sky for radio pulsars, using the 305 m telescope at Arecibo, Puerto Rico. The 430 MHz survey reached a limiting sensitivity for slow pulsars of 0.7 mJy using a dual-polarization, 32 channel filterbank over 8 MHz of ...

The Crucial First Step in the Discovery of Millisecond Pulsars [PDF]

Millisecond pulsars, like pulsars, have led to major advances in many areas of astronomy and physics. The discovery in 2023 of a cosmological gravitational wave (GW) stochastic background using millisecond pulsar timing arrays has focused attention on ...

The Anomalous Acceleration of PSR J2043+1711: Long-period Orbital Companion or Stellar Flyby?

The Astrophysical Journal
Based on the rate of change of its orbital period, PSR J2043+1711 has a substantial peculiar acceleration of 3.5 ± 0.8 mm s ^–1 yr ^–1 , which deviates from the acceleration predicted by equilibrium Milky Way (MW) models at a 4 σ level.
