Binary and Millisecond Pulsars

Living Reviews in Relativity, 2005
We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar ...

Beyond Accretion Limits: The Rise of Pulsating Gems

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT The discovery of several ultraluminous X‐ray sources exhibiting fast and rapidly evolving X‐ray pulsations unequivocally associates these sources with accreting neutron stars orbiting relatively massive companion stars (> 8M ⊙$$ {}_{\odot } $$).

Radio Observations of a Candidate Redback Millisecond Pulsar: 1FGL J0523.5-2529

The Open Journal of Astrophysics
Redback pulsars are a subclass of millisecond pulsar system with a low-mass non-degenerate companion star being ablated by the pulsar. They are of interest due to the insights they can provide for late-stage pulsar evolution during the recycling process.

Investigation for Binary Characteristics of LS I + 61°303 with Optical Polarization

The Astrophysical Journal
We investigate the optical linear polarization caused by Thomson scattering of the stellar radiation for gamma-ray binary LS I + 61°303, which likely contains a young pulsar.

Orbital modulation of emission of the binary pulsar J0737-3039B

, 2005
In binary radio pulsar system J0737-3039, slow pulsar B shows orbital modulations of intensity, being especially bright at two short orbital phases. We propose that these modulations are due to distortion of pulsar B magnetosphere by pulsar A wind which ...

A Lower Mass Estimate for PSR J0348+0432 Based on CHIME/Pulsar Precision Timing

The Astrophysical Journal Letters
The binary pulsar J0348+0432 was previously shown to have a mass of approximately 2 M _⊙ , based on the combination of radial-velocity and model-dependent mass parameters derived from high-resolution optical spectroscopy of its white-dwarf companion.

Born to be recycled: A comprehensive population synthesis of the Galactic millisecond pulsars

Astronomy & Astrophysics
Context. Millisecond pulsars (MSPs) are the oldest and fastest pulsars known to date. The first MSP to be discovered was PSR B1937+21 in 1982. To explain how these pulsars could be formed, a new hypothesis was formulated: the recycling of pulsars, i.e ...

Multi-Messenger Gravitational Wave Searches with Pulsar Timing Arrays: Application to 3C66B Using the NANOGrav 11-year Data Set [PDF]

, 2020
When galaxies merge, the supermassive black holes in their centers may form binaries and, during the process of merger, emit low-frequency gravitational radiation in the process. In this paper we consider the galaxy 3C66B, which was used as the target of

Recovering Pulsar Periodicity from Time-of-arrival Data by Finding the Shortest Vector in a Lattice

The Astrophysical Journal
The strict periodicity of pulsars is one of the primary ways through which their nature and environment can be studied, and it has also enabled precision tests of general relativity and studies of nanohertz gravitational waves using pulsar timing arrays (
