A pulsar-helium star compact binary system formed by common envelope evolution
Z. L. Yang, J. L. Han, D. J. Zhou +33
A stellar common envelope occurs in a binary system when the atmosphere of an evolving star expands to encompass an orbiting companion object. Such systems are predicted to evolve…

We present a polarization analysis of PSR J094139 and PSR J11075907, which exhibit transitions between being pulsars and rotating radio transients (RRATs), using the ultra-wi…
Searching for continuous Gravitational Waves in the second data release of the International Pulsar Timing Array
M. Falxa, S. Babak, P. T. Baker +123
The International Pulsar Timing Array 2nd data release is the combination of datasets from worldwide collaborations. In this study, we search for continuous waves: gravitational wa…
Arecibo and FAST Timing Follow-up of twelve Millisecond Pulsars Discovered in Commensal Radio Astronomy FAST Survey
C. C. Miao, W. W. Zhu, D. Li +46
We report the phase-connected timing ephemeris, polarization pulse profiles, Faraday rotation measurements, and Rotating-Vector-Model (RVM) fitting results of twelve millisecond pu…
