Abstract

We have recently detected a glitch in the spin of 1E 1207.4-5209, the compact central object (CCO) in SNR PKS 1209-51/52. This is entirely unexpected for a pulsar with a spin-down rate as small as those found for CCOs. Even more remarkable is the extreme change in its spin-down rate, which rivals those found for magnetars, NSs with surface magnetic fields 10,000 times greater than the dipole fields inferred for CCOs. The detection of a glitch therefore supports a recent conjecture that they could be triggered by the diffusion of a buried internal field. We propose to continue timing 1E 1207.4-5209, to verify the unexpected large change in its post-glitch spin-down rate.
