Measuring the Spin-Down and Dipole Magnetic Field of the CCO Pulsar 1E 1207.4-52

We propose to make a definite measurement of the spindown rate of the uniqueCCO pulsar 1E 1207.45209 by obtaining a phasecoherent timing solution, whichis the only feasible way of measuring the Pdot of such a weakly magnetized NS.1E 1207.45209 is the best isolated pulsar for which a direct comparison can bemade of its global dipole magnetic field via spindown, with the local Bfieldon the surface, as indicated by its cyclotron absorption spectrum. Existing datasuggest that these independent measures agree to within a factor of 4, with theabsence of a definite Pdot the limiting uncertainty. We can eliminate the erroron Pdot and determine if the Bfield measurements are identical for allpractical purposes in 1E 1207.45209, the prototypical antimagnetar. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
