Abstract
AbstractHigh-quality integrated radio profiles of some pulsars exhibit double, highly symmetric features both in emission and absorption. It is shown that both types of features are produced by a split-fan beam of extraordinary-mode curvature radiation (CR) that is emitted/absorbed by radially extended streams of magnetospheric plasma.With no emissivity in the plane of the stream, such a beam produces bifurcated emission components (BFCs) when our line of sight passes through the plane. This interpretation explains several observed properties of double features, such as their symmetry, shape, convergence rate and their high polarization degree. The stream-cut geometry also explains the lack of radius-to-frequency mapping in the millisecond pulsars.KeywordsRadio EmissionRadio PulsarCurvature BeamMillisecond PulsarElectron TrajectoryThese keywords were added by machine and not by the authors.
