Radio pulsars in binary systems

open access: yes, 2009
This thesis focuses on the study of binary radio pulsars, their evolution and some specific use of their properties to investigate fundamental physics such as general relativity and other gravitational theories. The work that we present here is organized

Polarization of Intrabinary Shock Emission in Spider Pulsars

open access: yesThe Astrophysical Journal, 2023
In so-called spider pulsars, the X-ray band is dominated by intrabinary shock (IBS) synchrotron emission. While the double-peaked X-ray light curves from these shocks have been well characterized in several spider systems (both black widows and redbacks),

Binary gamma-ray pulsars [PDF]

open access: yes, 2021
The first pulsar has been detected in 1967 as a seemingly pulsating radio source. Since then, more than 2800 pulsars have been discovered. Most of them also in radio. With the launch of the Fermi Gamma-ray Space Telescope in 2008, more than 250 gamma-ray

A Massive Pulsar in a Compact Relativistic Binary [PDF]

open access: yesScience, 2013
Pulsar Tests GravityBecause of their extremely high densities, massive neutron stars can be used to test gravity. Based on spectroscopy of its white dwarf companion,Antoniadiset al.(p.448) identified a millisecond pulsar as a neutron star twice as heavy as the Sun.

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.

Gravitoastronomy with neutron stars [PDF]

open access: yes, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.
