Abstract

The glitch or timing noise in the rotation of 1E 1207.4-5209, the central compact object (CCO) in SNR PKS 1209-51/52, is unprecedented for a pulsar with such a small spin-down rate. It may support a timely conjecture that glitches could be triggered in CCOs by diffusion of a strong, buried internal magnetic field that rivals in strength those found in magnetars, NSs with surface magnetic fields 10**4 times greater than the dipole fields inferred for CCOs. This proposal is to continue timing 1E 1207.4-5209 to distinguish glitches from timing noise, and to obtain a sufficiently precise measurement of its spin-down rate to test for a change in surface magnetic field strength. This may allow the first measurement of magnetic field growth on a CCO.
