A Massive Pulsar in a Compact Relativistic Binary [PDF]

open access: yesScience, 2013
Pulsar Tests Gravity Because of their extremely high densities, massive neutron stars can be used to test gravity. Based on spectroscopy of its white dwarf companion, Antoniadis et al.

Periodicity Search for Pulsar Binaries with TESS [PDF]

open access: yesThe Astrophysical Journal Letters, 2020
Abstract Pulsar binaries, in particular redback systems, provide good sources to study the pulsar wind flow and its interaction with the companion stars. Fermi-LAT have proposed probable pulsar binary candidates in its catalogs. An orbital modulation search of binary candidates is an effective way to identify pulsar binary sources from ...

Proton Acceleration with Relativistic Electromagnetic Shock. [PDF]

open access: yesAdv Sci (Weinh)
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

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.

Binary Pulsars [PDF]

open access: yesSymposium - International Astronomical Union, 1981
There are now three radio frequency pulsars known to be in binary systems: PSRs 1913+16, 0820+02, and 0655+64. The first of these, discovered in 1974, moves in a tight, highly eccentric orbit with a period of approximately 7h 45m. Its companion has not yet been identified with certainty, but must be a compact object of mass comparable to that of the ...

On the Detectability of Ultracompact Binary Pulsar Systems [PDF]

open access: yesThe Astrophysical Journal, 2021
Abstract Using neural networks, we integrate the ability to account for Doppler smearing due to a pulsar’s orbital motion with the pulsar population synthesis package psrpoppy to develop accurate modeling of the observed binary pulsar population.

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.

Recycled Pulsars [PDF]

open access: yes, 2005
We present the results of a large-area survey for millisecond pulsars (MSPs) at moderately high galactic latitudes with the 64 m Parkes radio telescope, along with follow-up timing and optical studies of the newly-discovered pulsars and several others ...

Binary and Other Recycled Pulsars [PDF]

open access: yesSymposium - International Astronomical Union, 1992
Binary pulsars and others with weak fields and rapid rotation now number several dozen and appear to have been spun up by close binary mass transfer. Some are lineal descendents of X-ray binaries; others may result from accretion-induced collapse of binary white dwarfs or from captures, exchanges, and collisions in clusters. Seven accurate neutron star
