Scintillation of the first-known pulsar planetary system
J. M. Yao, L. Zhang, A. Wolszczan +8
We present a scintillation study of the first-known pulsar planetary system, PSR~B1257+12, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). A total of 31 obs…
A study of periodic nulling in PSR B0751+32 with FAST
W. M. Yan, N. Wang, F. F. Kou +6
We report new results from a nulling study of PSR~B0751+32 (PSR J0754+3231), observed at 1250~MHz with the Five hundred meter Aperture Spherical radio Telescope (FAST). Our analysi…
The FAST Galactic Plane Pulsar Snapshot Survey. IX. Timing Three Binary Pulsars with Wide Orbits and Low Orbital Eccentricities
Z. L. Yang, J. L. Han, W. Q. Su +11
Current pulsar timing models face challenges when applied to binary pulsars with wide orbits and low orbital eccentricities. The conventional \texttt{DD} model accurately character…
Timing and scintillation of a young Galactic halo pulsar
J. M. Yao, F. F. Kou, J. P. Yuan +6
We present a timing and scintillation study of the young Galactic halo pulsar PSR J1740+1000 using observations from the Nanshan, FAST, and Parkes radio telescopes. From timing ana…
A Series of (Net) Spin-down Glitches in PSR J1522-5735: Insights from the Vortex Creep and Vortex Bending Models
S. Q. Zhou, W. T. Ye, M. Y. Ge +5
Through a detailed timing analysis of -LAT data, the rotational behavior of the -ray pulsar PSR J15225735 was tracked from August 2008 (MJD 54692) to January…
Follow-up timing of 12 pulsars discovered in Commensal Radio Astronomy FAST Survey
D. Zhao, J. P. Yuan, N. Wang +39
We present phase-connected timing ephemerides, polarization pulse profiles and Faraday rotation measurements of 12 pulsars discovered by the Five-hundred-meter Aperture Spherical r…
