The Centrifugal Acceleration and the Y-point of the Pulsar Magnetosphere

The Astrophysical Journal
We investigate the centrifugal acceleration in an axisymmetric pulsar magnetosphere under the ideal MHD approximation. We solve the field-aligned equations of motion for flows inside the current sheet with finite thickness. We find that flows coming into

Interpreting Mass and Radius Measurements of Neutron Stars with Dark Matter Halos

The Astrophysical Journal
The high densities of neutron stars (NSs) could provide astrophysical locations for dark matter (DM) to accumulate. Depending on the DM model, these DM admixed NSs (DANSs) could have significantly different properties than pure baryonic NSs, accessible ...

Chandra X-Ray Observations of PSR J1849-0001, Its Pulsar Wind Nebula, and the TeV Source HESS J1849-000

The Astrophysical Journal
We obtained a 108 ks Chandra X-ray Observatory (CXO) observation of PSR J1849-0001 and its pulsar wind nebula (PWN) coincident with the TeV source HESS J1849-000.

Luminosity Evolution of Rotation-powered Gamma-ray Pulsars

, 2013
We investigate the electrodynamic structure of a pulsar outer-magnetospheric particle accelerator and the resultant gamma-ray emission. By considering the condition for the accelerator to be self-sustained, we derive how the trans-magnetic-field thickness of the accelerator evolves with the pulsar age.

Polarized Multiwavelength Emission from Pulsar Wind—Accretion Disk Interaction in a Transitional Millisecond Pulsar

The Astrophysical Journal Letters
Transitional millisecond pulsars (tMSPs) bridge the evolutionary gap between accreting neutron stars in low-mass X-ray binaries and millisecond radio pulsars.

The Nature of the Ultrahigh-energy Source 1LHAASO J1740+0948u and Its Connection to PSR J1740+1000

The Astrophysical Journal
We present a multiwavelength analysis of 1LHAASO J1740+0948u and its surroundings including the pulsar wind nebula of middle-aged pulsar PSR J1740+1000.

Magnetosphere of the rotation-powered pulsar - A DC circuit model

The Astrophysical Journal, 1991
The global structure of the magnetosphere of rotation-powered pulsars is studied by analyzing a large-scale magnetospheric curent system. We assume that this current system forms a DC circuit which includes the electromotive source of the rotating neutron star and three loads : the outer gap, the pair-plasma wind, and the inner gap.
