HIDDEN MAGNETIC FIELDS IN NSs: KES 79 CCO REVISITED

We have recently detected a glitch in the spin of 1E 1207.45209, the compactcentral object (CCO) in SNR PKS120951/52, and possibly from a second CCO thatwe are monitoring, PSR J08214300 in SNR Puppis A. This is entirely unexpectedfor pulsars with a spindown rates as small as those found for CCOs. Thesedetections supports a recent conjecture that glitches could be triggered by thediffusion of a buried magnetar strength internal field, 10,000 larger than thedipole fields inferred for CCOs. Here, we propose to search for similar timinganomalies from the third known CCO pulsar, PSR J1852+0040 in SNR Kes 79. Adetection will reveal a general property of CCOs with important theoreticalimplications for NS Bfield structure and emission mechanisms, andevolution. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
