Accreting Millisecond X-Ray Pulsars [PDF]

open access: yes, 2013
Accreting Millisecond X-Ray Pulsars (AMXPs) are astrophysical laboratories without parallel in the study of extreme physics. In this chapter we review the past fifteen years of discoveries in the field.

Spin Equilibrium of Rapidly Spinning Neutron Stars via Transient Accretion

open access: yesGalaxies, 2023
The concept of spin equilibrium due to an interaction between the stellar magnetosphere and a thin, Keplerian accretion disk, and a well-known formula of the corresponding equilibrium spin frequency, provide a key understanding of spin evolution and the ...

Search for the Gravitational-wave Background from Cosmic Strings with the Parkes Pulsar Timing Array Second Data Release

open access: yesThe Astrophysical Journal, 2022
We perform a direct search for an isotropic stochastic gravitational-wave background (SGWB) produced by cosmic strings in the Parkes Pulsar Timing Array (PPTA) Data Release 2 (DR2).

Millisecond pulsar velocities [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1999
We present improved timing parameters for 13 millisecond pulsars (MSPs), including nine new proper motion measurements. These new proper motions bring to 23 the number of MSPs with measured transverse velocities. In light of these new results we present and compare the kinematic properties of MSPs with those of ordinary pulsars.

Electroporation safety factor of 300 nanosecond and 10 millisecond defibrillation in Langendorff-perfused rabbit hearts.

open access: yesPLoS ONE, 2021
AimsRecently, a new defibrillation modality using nanosecond pulses was shown to be effective at much lower energies than conventional 10 millisecond monophasic shocks in ex vivo experiments.

The Effect of Irradiation on the Spin of Millisecond Pulsars

open access: yesThe Astrophysical Journal Letters, 2023
A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.
