[118.04] Radio Polarization and Geometry of PSR J1119-6127

F. Crawford, N. C. Keim (Haverford College)

Using 1400-MHz archival data from the Parkes radio telescope, we present radio polarization characteristics for PSR J1119-6127, a very young pulsar notable for its large magnetic field. We compare the polarization features of PSR J1119-6127 with those of other young pulsars (e.g., PSR J1513-5908) and discuss the pulsar in the context of a recent theoretical model of pulsar spin-down; this spin-down model can in principle be tested with polarization and timing data from this pulsar. Constraints on the pulsar's emission geometry obtained from a rotating vector model fit to the available position angle data are not sufficient to test the spin-down model, but additional data may allow a significant test in the future.
