Aspects of mass transfer in X-ray binaries: a model for three classes of binary millisecond pulsars

, 1996
The possibility that some close binary systems in their X-ray phase evolve into a second common envelope and spiral-in phase is very important for the formation of short orbital period binary millisecond pulsars.

Manifestations of Horndeski theory in binary systems with pulsars.

, 2018
Subclass of Horndeski gravity without Vainstein screening mechanism is tested in strong field regime of binary pulsars. Two specific cases of the Horndeski gravity are considered: the hybrid metric-Palatini f(R)-gravity and massive Brans-Dicke theory ...

XMM-Newton Observation and Optical Monitoring of the Candidate Redback Millisecond Pulsar 1FGL J0523.5-2529

The Astrophysical Journal
1FGL J0523.5−2529 is a Fermi selected redback millisecond pulsar candidate that exhibited luminous optical and X-ray flares in 2020–2021. We obtained a simultaneous X-ray and U -band observation with XMM-Newton in 2025, the first to cover the 16.5 hr ...

Discovering Pulsars in Compact Binaries with a Hidden Markov Model

The Astrophysical Journal
Discovering radio pulsars in compact binaries, whose orbital periods P _b satisfy P _b ≲ 1 day, is computationally challenging, because the time-dependent pulse frequency f _p ( t ) is strongly Doppler modulated by the binary motion.

Detection of binary pulsars with GPU-accelerated sinusoidal Hough transformations. [PDF]

, 2013
Analysis of relativistic binary pulsars is currently the best means by which to test theories of gravity in strong gravitational fields. Four-dimensional Hough transformations can detect sinusoids in noisy images.

Temporal Variations in Pulsar Spectropolarimetry: Findings from Millisecond Pulsar J2144–5237 Using Parkes UWL Receiver

The Astrophysical Journal
While the temporal variations of the spectropolarimetric nature of pulsars remain unexplored, this investigation offers significant potential for uncovering key insights into pulsar emission mechanisms, magnetic field geometry, and propagation effects ...

The detectability of eccentric binary pulsars

, 2014
Studies of binary pulsars provide insight into various theories of physics. Detection of such systems is challenging due to the Doppler modulation of the pulsed signal caused by the orbital motion of the pulsar. We investigated the loss of sensitivity in eccentric binary systems for different types of companions. This reduction of sensitivity should be

A 350 MHz Green Bank Telescope Survey of Unassociated Fermi LAT Sources: Discovery and Timing of 10 Millisecond Pulsars

The Astrophysical Journal
We have searched for radio pulsations toward 49 Fermi Large Area Telescope (LAT) 1FGL Catalog γ -ray sources using the Green Bank Telescope at 350 MHz. We detected 18 millisecond pulsars (MSPs) in blind searches of the data; 10 of these were discoveries ...
