The period-width relationship for radio pulsars revisited.

JOHNSTON S. and KARASTERGIOU A.

Abstract (from CDS):

In the standard picture of radio pulsars, the radio emission arises from a set of open magnetic field lines, the extent of which is primarily determined by the pulsar's spin period, P, and the emission height. We have used a data base of parameters from 600 pulsars to show that the observed profile width, W, follows W ∝ P–0.3 albeit with a large scatter, emission occurs from heights below 400 km and that the beam is underfilled. Furthermore, the prevalence in the data for long-period pulsars to have relatively wide profiles can only be explained if the angle between the magnetic and rotation axis decays with time.
