Discovery of five binary radio pulsars

The Astrophysical Journal, 2001
We report on five binary pulsars discovered in the Parkes multibeam Galactic plane survey. All of the pulsars are old, with characteristic ages (1-11) x 10(9) yr, and have relatively small inferred magnetic fields, (5-90) x 10(8) G.

Discovery of Three Binary Millisecond Pulsars

The Astrophysical Journal, 1994
We report the discovery of three binary millisecond pulsars in circular orbits with low-mass companions from a continuing survey of the southern sky with the Parkes radio telescope.

A binary pulsar in a 53-minute orbit. [PDF]

Nature, 2023
AbstractSpider pulsars are neutron stars that have a companion star in a close orbit. The companion star sheds material to the neutron star, spinning it up to millisecond rotation periods, while the orbit shortens to hours. The companion is eventually ablated and destroyed by the pulsar wind and radiation1,2.

Binary evolution and formation of binary millisecond pulsars.

, 1994
The high incidence of binaries among millisecond pulsars in combination with rapid spin and relatively weak magnetic fields strongly suggest a large fraction of them (if not all) are old neutron stars that have been 'recycled' by accretion of mass and ...

Proton Acceleration with Relativistic Electromagnetic Shock. [PDF]

Adv Sci (Weinh)
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Radio pulsars in binary systems

, 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

A Massive Pulsar in a Compact Relativistic Binary [PDF]

Science, 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.

Periodicity Search for Pulsar Binaries with TESS [PDF]

The Astrophysical Journal Letters, 2020
Abstract Pulsar binaries, in particular redback systems, provide good sources to study the pulsar wind flow and its interaction with the companion stars. Fermi-LAT have proposed probable pulsar binary candidates in its catalogs. An orbital modulation search of binary candidates is an effective way to identify pulsar binary sources from ...

On the Detectability of Ultracompact Binary Pulsar Systems [PDF]

The 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.

Recycled Pulsars [PDF]

, 2005
We present the results of a large-area survey for millisecond pulsars (MSPs) at moderately high galactic latitudes with the 64 m Parkes radio telescope, along with follow-up timing and optical studies of the newly-discovered pulsars and several others ...
