Axion resonances in binary pulsar systems [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2019
We investigate the extent to which resonances between an oscillating background of ultra-light axion and a binary Keplerian system can affect the motion of the latter.

Interpretation of Binary Pulsar Observations [PDF]

open access: yesSymposium - 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 ...

Radiation Dosimetry of Binary Pulsars [PDF]

open access: yesThe Astrophysical Journal, 1996
Companion stars exposed to high energy radiation from a primary neutron star or accreting black hole can experience significant spallation of their heavy elements, so that their atmospheres would be extremely rich in lithium, beryllium, and especially boron. In this paper we note that the detection or non-detection of these elements, and their relative

Constraints on Undetected Long-period Binaries in the Known Pulsar Population

open access: yesThe Astrophysical Journal, 2023
Although neutron star–black hole binaries have been identified through mergers detected in gravitational waves, a pulsar–black hole binary has yet to be detected.

Optical Identification of the Shortest-period Spider Pulsar System M71E

open access: yesThe Astrophysical Journal, 2023
M71E is a spider pulsar (i.e., a millisecond pulsar with a tight binary companion) with the shortest known orbital period of P = 53.3 minutes, which was discovered by Pan et al.

A pulsar in a binary with a compact object in the mass gap between neutron stars and black holes [PDF]

open access: yesScience
Some compact objects observed in gravitational wave events have masses in the gap between known neutron stars (NSs) and black holes (BHs). The nature of these mass gap objects is unknown, as is the formation of their host binary systems. We report pulsar

Discovery and Timing of Millisecond Pulsars in the Globular Cluster M5 with FAST and Arecibo

open access: yesThe Astrophysical Journal Supplement Series, 2023
We report on a comprehensive multiwavelength study of the pulsars in the globular cluster (GC) M5, including the discovery of M5G, a new compact noneclipsing “black widow” pulsar.

The High Time Resolution Universe Pulsar Survey - XIII. PSR J1757-1854, the most accelerated binary pulsar [PDF]

open access: yes, 2017
We report the discovery of PSR J1757$-$1854, a 21.5-ms pulsar in a highly-eccentric, 4.4-h orbit around a neutron star (NS) companion. PSR J1757$-$1854 exhibits some of the most extreme relativistic parameters of any known pulsar, including the strongest

Decade long RXTE monitoring observations of Be/X-ray binary pulsar EXO 2030+375 [PDF]

open access: yes, 2017
We present a comprehensive timing and spectral studies of Be/X-ray binary pulsar EXO 2030+375 using extensive Rossi X-ray Timing Explorer observations from 1995 till 2011, covering numerous Type I and 2006 Type II outbursts.
