Contents
Contents Anomalous X-ray Pulsars

  • Brief introduction to the timing feature of AXP

  • Introduction to pulsar glitches and the post-glitch recovery

  • Explanations for the age problem of PSR B1757-24

  • The fate of PSR B1757-24 (a future candidate of Anomalous X-ray Pulsar).

  • Conclusions and discussion

Conclusions and discussion
Conclusions and discussion emission (Kaspi et al. 2001)

  • New model bases on observation; glitches

  • We should carefully estimate the pulsars’ ages

  • the fate of a pulsar depends on its post-glitch recovery type.

  • The population of AXPs given by our model is reasonable.
