Evolution of the X-ray Profile of the Crab Pulsar
M. Y. Ge, L. L. Yan, F. J. Lu +5
Using the archive data from the Rossi X-ray Timing Explorer ({\sl RXTE}), we have studied the evolution of the X-ray profile of the Crab pulsar in a time span of 11 years. The X-ra…
Phase Evolution of the Crab Pulsar between Radio and X-ray
L. L. Yan, M. Y. Ge, J. P. Yuan +8
We study the X-ray phases of the Crab pulsar utilizing the 11-year observations from the Rossi X-ray Timing Explorer, 6-year radio observations from the Nanshan Telescope, and the…
Fluctuating neutron star magnetosphere: braking indices of eight pulsars, frequency second derivatives of 222 pulsars and 15 magnetars
Z. W. Ou, H. Tong, F. F. Kou +1
Eight pulsars have low braking indices, which challenge the magnetic dipole braking of pulsars. 222 pulsars and 15 magnetars have abnormal distribution of frequency second derivati…
Rotational evolution of the Crab pulsar in the wind braking model
F. F. Kou, H. Tong
The pulsar wind model is updated by considering the effect of particle density and pulsar death. It can describe both the short term and long term rotational evolution of pulsars c…
Wind braking of magnetars: to understand magnetar's multiwave radiation properties
H. Tong, R. X. Xu
Magnetars are proposed to be peculiar neutron stars powered by their super strong magnetic field. Observationally, anomalous X-ray pulsars and soft gamma-ray repeaters are believed…
Is magnetar a fact or fiction to us?
H. Tong, R. X. Xu
The key point of studying AXPs/SGRs (anomalous X-ray pulsars/soft gamma-ray repeaters) is relevant to the energy budget. Historically, rotation was thought to be the only free ener…
What can Fermi tell us about magnetars?
H. Tong, R. X. Xu
We have analyzed the physical implications of Fermi observations of magnetars. Observationally, no significant detection is reported in Fermi observations of all magnetars. Then th…
SGR 0418+5729: a small inclination angle resulting in a not so low dipole magnetic field?
H. Tong, R. X. Xu
The spin down behaviors of SGR 0418+5729 are investigated. The pulsar spin down model of Contopoulos & Spitkovsky (2006) is applied to SGR 0418+5729. It is shown that SGR 0418+5729…
AXPs and SGRs in the outer gap model: confronting Fermi observations
H. Tong, L. M. Song, R. X. Xu
Anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are magnetar candidates, i.e., neutron stars powered by strong magnetic field. If they are indeed magnetars, they…
Non-detection in a Fermi/LAT observation of AXP 4U 0142+61: magnetars?
H. Tong, L. M. Song, R. X. Xu
Significant research in compact stars is currently focused on two kinds of enigmatic sources: anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs). Although AXPs and…
