Rotating twisted magnetosphere of magnetars: approximate analytical solutions
H. Tong, L. Chen
An approximate analytical solution for the rotating twisted magnetosphere of magnetars is presented. The poloidal flux is approximated by the self-similar twisted dipole field. The…

Pulsar radio emission height as a function of phase
H. Tong, H. G. Wang
We present an analytical treatment of the pulsar radio emission height as a function of phase based on a set of simplifying assumptions. Assuming a dipole field geometry, the emiss…

Precession for the mode change in a gamma-ray pulsar
H. Tong, H. H. Wang
PSR J2021+4026 is a gamma-ray pulsar having variations in its spin-down rate and gamma-ray flux. Its variations in timing and emission are correlated, e.g., a larger spin-down rate…
