Abstract

The detection of glitches or timing noise in the rotation of central compact objects (CCOs) in SNRs is unprecedented for pulsars with such small spin-down rates. 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 10,000 times greater than the dipole fields inferred for CCOs. This proposal is to continue timing 1E1207.4-5209 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 to compare to theoretical models.
