Mechanism for Radio Emission of Pulsars

摘要

This is a review of work upon which a proposal for an effective mechanism for the radio emission of pulsars is based. It is shown that spin-down of a neutron star makes the system of proton vortices move toward the surface of the star's core. The magnetic energy of these vortices is released in "magnetic caps" of limited size located on the core surface and crust of neutron stars. Magnetosonic waves propagating in the crust of the star transfer this energy to its surface and form a localized source of radio emission in pulsars. Because of the star's rotation the emission from this source will pulsate. Some observed properties of the radio emission from pulsars can be explained by the proposed emission mechanism.
