PSR J2150+3427: A Possible Double Neutron Star System
The Astrophysical Journal Letters, 2023 PSR J2150+3427 is a 0.654 s pulsar discovered by the Commensal Radio Astronomy FAST Survey. From the follow-up observations, we find that the pulsar is in a highly eccentric orbit ( e = 0.601) with an orbital period of 10.592 days and a projected ...

Radio pulsar binaries in globular clusters: their orbital eccentricities and stellar interactions
, 2009 High sensitivity searches of globular clusters (GC) for radio pulsars by improved pulsar search algorithms and sustained pulsar timing observations have so far yielded some 140 pulsars in more than two dozen GCs.

The Green Bank North Celestial Cap Survey. VIII. 21 New Pulsar Timing Solutions
The Astrophysical Journal, 2023 We present timing solutions for 21 pulsars discovered in 350 MHz surveys using the Green Bank Telescope (GBT). All were discovered in the Green Bank North Celestial Cap pulsar survey, with the exception of PSR J0957−0619, which was found in the GBT 350 ...

The origin of single radio pulsars
, 1999 By comparing relative rates of supernovae versus formation rates of single radio pulsars, recycled pulsars, binary pulsars and X-ray binaries we put strong limits on the progenitors of radio pulsars and on the requirement of an asymmetry in the supernova.

Catalog of the Galactic Population of X-Ray Pulsars in High-mass X-Ray Binary Systems
The Astrophysical Journal Supplement Series, 2023 A catalog of the Galactic population of X-ray pulsars in high-mass X-ray binary (HMXB) systems is presented. It contains information about 82 confirmed sources: 18 persistent and 64 transient pulsars.

Formation of Short-Period Binary Pulsars in Globular Clusters [PDF]
, 1999 We present a new dynamical scenario for the formation of short-period binary millisecond pulsars in globular clusters. Our work is motivated by the recent observations of 20 radio pulsars in 47 Tuc.

Millisecond Pulsars, their Evolution and Applications
, 2017 Millisecond pulsars (MSPs) are short-period pulsars that are distinguished from "normal" pulsars, not only by their short period, but also by their very small spin-down rates and high probability of being in a binary system.

Interpretation of Binary Pulsar Observations [PDF]
Symposium - International Astronomical Union, 1981 The nature, dynamics and evolution of the three known radio pulsar binaries are discussed. The system containing 1913+16 appears to comprise two ~1.4 M⊙ components, and to undergo orbital decay as predicted by general relativity. It is proposed that 1913+16 has a neutron star companion and that 0655+64 and 0820+02 have white dwarf companions which ...

Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters
The Astrophysical JournalGlobular clusters (GCs) are particularly efficient at forming millisecond pulsars. Among these pulsars, about half lack a companion star, a significantly higher fraction than in the Galactic field.
