Modeling Multi-wavelength Pulse Profiles of Millisecond Pulsar PSR B1821-24

Yuanjie Du, Guojun Qiao, Ping Shuai +10

PSR B182124 is a solitary millisecond pulsar (MSP) which radiates multi-wavelength pulsed photons. It has complex radio, X-ray and -ray pulse profiles with distinct peak phas…

AXPs & SGRs: Magnetar or Quarctar?

Guojun Qiao, Xiongwei Liu, Renxin Xu +4

The concept of a "magnetar" was proposed mainly because of two factors. First, the X-ray luminosity of Anomalous X-ray Pulsars (AXPs) and Soft Gamma-Ray Repeaters (SGRs) is larger…

Braking PSR J1734-3333 with a possible fall-back disk

X. W. Liu, R. X. Xu, G. J. Qiao +2

The very small braking index of PSR J1734-3333, , challenges the current theories of braking mechanisms in pulsars. We present a possible interpretation that this puls…

Wind braking of magnetars

H. Tong, R. X. Xu, L. M. Song +1

(adapted)Considering recent observations challenging the traditional magnetar model, we explore the wind braking of magnetars. There is evidence for strong multipole magnetic field…

Radio-to-TeV Phase-resolved Emission from the Crab Pulsar: The Annular Gap Model

YuanJie Du, GuoJun Qiao, Wei Wang

In the framework of the three-dimensional (3D) annular gap model with reasonable parameters (the magnetic inclination angle α= 45 deg and the view angle ζ= 63 deg), we first use th…

Pulsars and Gravitational Waves

K. J. Lee, R. X. Xu, G. J. Qiao

The relationship between pulsar-like compact stars and gravitational waves is briefly reviewed. Due to regular spins, pulsars could be useful tools for us to detect ~nano-Hz low-fr…
