Pulsar electrodynamics: cylindrical model and radio and gamma-ray radiation

A. A. da Costa

Open full text 10 citations

Abstract

Magnetospheres of pulsars contain charged particles. The motion of electrons and positrons in a simplified cylindrical model is discussed for pulsars with three different periods. It will be shown that this motion near the region E = cB provides not only a mechanism for the production of incoherent radiation at gamma-ray frequencies but also the basis to explain the radio emission. A single region to explain the radiation in both frequency domains is supported by observations of the Crab Pulsar.
