Comprehensive Measurement of Position and Velocity in the Transverse Direction Using the Crab Pulsar
AerospaceTraditional X-ray pulsar ranging and velocity measurement methods only estimate the radial position and velocity information of the pulsar. For non-linear orbits, errors in the transverse position and velocity of the pulsar lead to errors in the radial ...

Propagation of X-ray and gamma ray emissions in strong magnetic and gravitational fields
Physical Sciences and Technology, 2016 We consider the propagation of X-ray and gamma ray emissions in strong magnetic and gravitational fields of the pulsar in nonlinear vacuum electrodynamics. We show that the radiation has birefrigence.

On the overall properties of young neutron stars: an application to the Crab pulsar
Frontiers in Astronomy and Space SciencesIn this brief report, we present a model that complements the well-established canonical model for the spin evolution of rotation-powered pulsars, which is typically used to estimate ages, spin-down luminosity, and surface magnetic fields of middle-aged ...

Identifying Companions in Pulsar Binary Systems via Gaia Data
UniverseIn 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.

A Lower Mass Estimate for PSR J0348+0432 Based on CHIME/Pulsar Precision Timing
The Astrophysical Journal LettersThe 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.
