On the braking index evolution of PSR B0540-69: wind braking of pulsars
H. Tong
The pulsar PSR B0540-69 has both a braking index measurement and spin-down state change. After its spin-down state change, it shows an increasing braking index with time. Previousl…

On the Difference Between Pulsar Radio Emission Beams from the Two Poles
Xiancong Wu, Hongguang Wang, Hao Tong +4
The long-standing assumption of symmetric radio emission beams from the two magnetic poles of pulsars is challenged by observational evidence of asymmetry and underfill. Direct tes…

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…
