Proper Motion of the Crab Pulsar Revisited
arXiv:astro-ph/0602255 · doi:10.1086/503315
Abstract
It has been suggested that the Crab pulsar's proper motion is well aligned with the symmetry axis of the pulsar wind nebula. We have re-visited this question, examining over 6 years of F547M WFPC2 chip 3 images to obtain a best-fit value of mas/yr at PA $278\arcdeg \pm 3\arcdeg$. At $26\arcdeg\pm 3\arcdeg$ to the nebula axis, this substantially relaxes constraints on the birth kick of this pulsar. Such misalignment allows the momentum to be imparted over 1s timescales.
