ON THE TRANSITION FROM ACCRETION-POWERED TO ROTATION-POWERED MILLISECOND PULSARS [PDF]

The Astrophysical Journal, 2010
The heating associated with the deposition of $ $-rays in an accretion disk is proposed as a mechanism to facilitate the transformation of a low mass X-ray binary to the radio millisecond pulsar phase. The $ $-ray emission produced in the outer gap accelerator in the pulsar magnetosphere likely irradiates the surrounding disk, resulting in its ...

Swings between rotation and accretion power in a binary millisecond pulsar [PDF]

Nature, 2013
It is thought that neutron stars in low-mass binary systems can accrete matter and angular momentum from the companion star and be spun-up to millisecond rotational periods. During the accretion stage, the system is called a low-mass X-ray binary, and bright X-ray emission is observed.

X-RAY AND GAMMA-RAY EMISSIONS FROM ROTATION POWERED MILLISECOND PULSARS [PDF]

The Astrophysical Journal, 2012
The Fermi Large Area Telescope has revealed that rotation powered millisecond pulsars (MSPs) are a major contributor to the Galactic {gamma}-ray source population. Such pulsars may also be important in modeling the quiescent state of several low-mass X-ray binaries (LMXBs), where optical observations of the companion star suggest the possible existence

Efficiency of Synchrotron Radiation from Rotation-powered Pulsars [PDF]

The Astrophysical Journal, 2017
Abstract Synchrotron radiation is widely considered to be the origin of the pulsed non-thermal emissions from rotation-powered pulsars in optical and X-ray bands. In this paper, we study the synchrotron radiation emitted by the created electron and positron pairs in the pulsar magnetosphere to constrain the energy conversion efficiency ...

Spin frequency distributions of binary millisecond pulsars [PDF]

, 2014
Rotation-powered millisecond radio pulsars have been spun up to their present spin period by a $10^8$ - $10^9$ yr long X-ray-bright phase of accretion of matter and angular momentum in a low-to-intermediate mass binary system.

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars

The Astrophysical Journal, 2023
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

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-

The Polarized Cosmic Hand: IXPE Observations of PSR B1509−58/MSH 15−52

The Astrophysical Journal, 2023
We describe IXPE polarization observations of the pulsar wind nebula (PWN) MSH 15−5 ^2 , the “Cosmic Hand.” We find X-ray polarization across the PWN, with B -field vectors generally aligned with filamentary X-ray structures.

X-ray properties of rotation-powered pulsars [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractRadiation of most of the known pulsars is powered by the loss of their rotational energy and angular momentum. Thanks to the Chandra and XMM-Newton observatories, X-ray emission has been detected from over 100 rotation-powered pulsars in the last 12 years.

The glitch activity of rotation-powered pulsars [PDF]

Proceedings of the International Astronomical Union, 2017
AbstractA statistical study of the glitch population and the behavior of the glitch activity across the known population of neutron stars is presented. A constant ratio between the glitch activity and the spin-down rate $\dot{\nu }_{\rm {g}}$/|$\dot{\nu }$| = 0.010 ± 0.001 is consistent with the behavior of all rotation-powered pulsars and magnetars ...
