Millisecond Pulsars in M2: New Discoveries and a Detailed Timing Analysis

The Astrophysical Journal
Globular clusters (GCs) offer a unique environment for discovering and studying millisecond pulsars. In this paper, we present a multiepoch search and detailed timing analysis of millisecond pulsars in the GC M2, using the Five-hundred-meter Aperture ...

Optical pulsations from a transitional millisecond pulsar [PDF]

, 2017
Weakly magnetic, millisecond spinning neutron stars attain their very fast rotation through a 1E8-1E9 yr long phase during which they undergo disk-accretion of matter from a low mass companion star. They can be detected as accretion-powered millisecond X-

High Energy Gamma-rays from Globular Clusters [PDF]

, 2007
It is expected that specific globular clusters can contain up to a hundred of millisecond pulsars. These pulsars can accelerate leptons at the shock waves originated in collisions of the pulsar winds and/or inside the pulsar magnetospheres.

The Relationships between Emission Geometry and Jitter Noise in Millisecond Pulsars

The Astrophysical Journal
The relationships between several parameters of an emission geometry and jitter noise in 17 millisecond pulsars (MSPs) are investigated. By assuming the jitter noise is due only to a pulse variation in phase, the former can be modeled as changes in the ...

Probing neutron star physics using accreting neutron stars

EPJ Web of Conferences, 2010
We give an obervational overview of the accreting neutron stars systems as probes of neutron star physics. In particular we focus on the results obtained from the periodic timing of accreting millisecond X-ray pulsars in outburst and from the ...

A Search for Sub-Millisecond Pulsars

, 2001
We have conducted a search of 19 southern Galactic globular clusters for sub-millisecond pulsars at 660 MHz with the Parkes 64-m radio telescope. To minimize dispersion smearing we used the CPSR baseband recorder, which samples the 20 MHz observing band ...

Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters

The Astrophysical Journal
Globular clusters (GCs) are particularly efficient at forming millisecond pulsars. Among these pulsars, about half lack a companion star, a significantly higher fraction than in the Galactic field.

On the progenitors of millisecond pulsars by the recycling evolutionary channel

, 2011
The recycling model suggested that low-mass X-ray binaries (LMXBs) could evolve into binary millisecond pulsars (BMSPs). In this work, we attempt to investigate the progenitor properties of BMSPs formed by the recycling evolutionary channel, and if sub ...

The Green Bank North Celestial Cap Survey. VIII. 21 New Pulsar Timing Solutions

The Astrophysical Journal, 2023
We present timing solutions for 21 pulsars discovered in 350 MHz surveys using the Green Bank Telescope (GBT). All were discovered in the Green Bank North Celestial Cap pulsar survey, with the exception of PSR J0957−0619, which was found in the GBT 350 ...
