Monitoring the Extraordinary Timing Behavior of CCO Pulsars

CCO pulsars are stable rotators with weak dipole Bfields and small spindownrates, and are only detected in Xrays. We have been timing two CCO pulsars for20 years. Surprisingly, we detected a glitch in the CCO 1E 1207.45209, which isunprecedented for any pulsar with such a small spindown rate. This has profoundimplications for both the Bfield evolution of CCOs and the mechanisms thattrigger glitches. We are starting to see similar features in the timing of theCCO PSR J08214300 in Puppis A, and propose here to continue timing it todistinguish between glitch activity and an alternative of accretion torque noiseat a very low level from fallback disks around CCOs. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
