Binary system delays and timing noise in searches for gravitational waves from known pulsars [PDF]

, 2007
The majority of fast millisecond pulsars are in binary systems, so that any periodic signal they emit is modulated by both Doppler and relativistic effects.

The Effect of Irradiation on the Spin of Millisecond Pulsars

The Astrophysical Journal Letters, 2023
A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.

Exploring the Extra Component in the Gamma-ray Emission of the New Redback Candidate 3FGL J2039.6-5618 [PDF]

Journal of Astronomy and Space Sciences, 2016
A redback system is a binary system composed of a pulsar and a main sequence star. The inverse Compton (IC) scattering between the stellar soft photons and the relativistic pulsar wind will generate orbital-modulating GeV photons.

Populating the Galaxy with pulsars I: stellar & binary evolution

, 2008
The computation of theoretical pulsar populations has been a major component of pulsar studies since the 1970s. However, the majority of pulsar population synthesis has only regarded isolated pulsar evolution.

Furnishing the Galaxy with Pulsars

, 2007
The majority of pulsar population synthesis studies performed to date have focused on isolated pulsar evolution. Those that have incorporated pulsar evolution within binary systems have tended to either treat binary evolution poorly of evolve the pulsar ...

Probing the properties of the pulsar wind via studying the dispersive effects in the pulses from the pulsar companion in a double neutron-star binary system [PDF]

, 2017
The velocity and density distribution of $e^\pm$ in the pulsar wind are crucial distinction among magnetosphere models, and contains key parameters determining the high energy emission of pulsar binaries.

Identifying Companions in Pulsar Binary Systems via Gaia Data

Universe
In the optical band, very few pulsars can be directly detected, but some of the pulsar binary companions can be observed. This study leverages high-precision astrometric data from Gaia Data Release 3 (DR3) to identify pulsar companions in binary systems.

Bits Missing: Finding Exotic Pulsars Using bfloat16 on NVIDIA GPUs

The Astrophysical Journal Supplement Series, 2023
The Fourier domain acceleration search (FDAS) is an effective technique for detecting faint binary pulsars in large radio astronomy data sets. This paper quantifies the sensitivity impact of reducing numerical precision in the graphics processing unit ...

Binary pulsars as dark-matter probes

, 2015
During the motion of a binary pulsar around the Galactic center, the pulsar and its companion experience a wind of dark-matter particles that can affect the orbital motion through dynamical friction.
