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…
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…
A Generic Model for Persistent Radio Source around Fast Radio Bursts
Yushan Chen, Hao Tong
The repeated fast radio burst FRB 121102A and FRB 190520B has been reported, along with a spatially coincident, compact, persistent radio emission. In this paper, we present a para…
Rotating vector model and radius-to-frequency mapping in the presence of multipole magnetic field
J. L. Qiu, H. Tong, H. G. Wang
The rotating vector model and radius-to-frequency mapping in the presence of multipole magnetic field in pulsars and magnetars are considered. An axisymmetric potential field is as…
On the nature of long period radio pulsar GPM J183910: death line and pulse width
H. Tong
Recently another long period radio pulsar GPM J183910 is reported, similar to GLEAM-X J162759.5523504.3. Previously, the energy budget and rotational evolution of long period…
A note on the anti-glitch of magnetar SGR 1935+2154
H. Tong
The magnetar SGR 1935+2154 is reported to have an anti-glitch, accompanied by fast radio bursts, and transient pulsed radio emission. In the wind braking model, this triplet event…
Large polar caps for twisted magnetosphere of magnetars
H. Tong
The magnetic field of magnetars may be twisted compared with that of normal pulsars. Previous works mainly discussed magnetic energy release in the closed field line regions of mag…
Rotational Evolution of The Slowest Radio Pulsar PSR J0250+5854
F. F. Kou, H. Tong, R. X. Xu +1
We apply theoretical spin-down models of magnetospheric evolution and magnetic field decay to simulate the possible evolution of PSR J0250+5854, which is the slowest-spinning radio…
