Relativistic effects of PSR~J1856--0039 double neutron star system in a 2.36-hour compact orbit

Z. L. Yang, J. L. Han, W. Q. Su +11

Compact double neutron star (DNS) systems are unique laboratories for testing gravitational theories and studying DNS mergers. Here we report the properties of a new DNS system, PS…

FAST Pulsar Database III. Snapshots of nulling, mode-changing and subpulse modulation of 374 pulsars

Yi Yan, J. L. Han, J. Xu +8

Based on sensitive L-band (1.0 to 1.5 GHz) observations of pulsars using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we analyzed single-pulse sequences from F…

FAST Pulsar Database IV. Spike subpulses and quasi-periodic subpulses of 25 pulsars observed by FAST

Tao Wang, N. N. Cai, J. L. Han +6

Fine structures of individual pulses can be detected when observations are conducted with a high time resolution and a great sensitivity. We examined pulsar data observed by the Fi…

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…

Mass measurements of the double neutron star system PSR J0641+0448

Z. L. Yang, J. L. Han, P. F. Wang +8

Pulsar timing of double neutron star (DNS) systems is one of the best methodologies to study the neutron star masses distribution. Here we report the discovery of a double neutron…

A nearby pulsar J1951+2837 observed by the LPA and FAST

T. V. Smirnova, D. J. Zhou, M. A. Kitaeva +5

PSR J1951+2837 is a nearby pulsar with a period of 7.334 s and dispersion measure of DM = 2.9 0.6 pc cm, located about 200 or 300 pc from the Sun. It occasionally radi…
