Pulsar Polar Cap and Slot Gap Models: Confronting Fermi Data [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
Rotation-powered pulsars are excellent laboratories for studying particle acceleration as well as fundamental physics of strong gravity, strong magnetic fields and relativity.

Pulsars and gravity [PDF]

open access: yesInternational Journal of Modern Physics D, 2006
Pulsars are wonderful gravitational probes. Their tiny size and stellar mass give their rotation periods a stability comparable to that of atomic frequency standards. This is especially true of the rapidly rotating "millisecond pulsars" (MSPs). Many of these rapidly rotating pulsars are in orbit with another star, allowing pulsar timing to probe ...

Gravity Tests with Radio Pulsars

open access: yesUniverse, 2020
The discovery of the first binary pulsar in 1974 has opened up a completely new field of experimental gravity. In numerous important ways, pulsars have taken precision gravity tests quantitatively and qualitatively beyond the weak-field slow-motion ...

Gamma-ray emission from millisecond pulsars - an Outergap perspective [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
In this review paper we explain the following gamma-ray emission features from the millisecond pulsars. (1) Why is the dipolar field of millisecond pulsars so weak but the magnetic pair creation process may still be able to control the size of the ...

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 ...

Pulsars and Magnetars [PDF]

open access: yesBrazilian Journal of Physics, 2013
The high-energy sources known as anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are well explained as magnetars: isolated neutron stars powered by their own magnetic energy. After explaining why it is generally believed that the traditional energy sources at work in other neutron stars (accretion, rotation, residual heat) cannot ...

Pulsar Electrodynamics — Pulsars and Puzzlers — [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
AbstractA gedanken experiment presented here provides basic understanding of how the pulsar magnetosphere operates. We discuss current issues about the electric-field acceleration along magnetic field lines and subsequent pair creation, and also about the pulsar wind problem.

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

open access: yesThe 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

Possible Distance Indicators in Gamma-ray Pulsars [PDF]

open access: yes, 2011
Distance measurements of gamma-ray pulsars are challenging questions in present pulsar studies. The Large Area Telescope (LAT) aboard the Fermi gamma-ray observatory discovered more than 70 gamma-ray pulsars including 24 new gamma-selected pulsars which nearly have no distance information.
