Emission from Closed and Filled Magnetospheric Shells and Its Application to the Crab Pulsar
Abstract
An earlier examination by B. Miller and B. J. Eastlund (1996) of coherent radio emission from particles confined to closed and filled magnetospheric shells that approach the light cylinder of a pulsar is extended to include incoherent emission from energetic charged particles, similarly confined. The emitting particles are now also postulated to be electrostatically mirroring in the pulsar's magnetic field. This model generates time-averaged pulse shapes that resemble closely those from the Crab pulsar, over 14 orders of magnitude of frequency, and matches the observed power spectrum over the same frequency range.
