On the Emission Region of Type II Radio Bursts in Interplanetary Shock Fronts

Abstract:

We analyze Type II radio emissions observed by the Radio and Plasma Waves instrument onboard Wind to determine the emission region in shock fronts, using the blast wave reconstruction technique. Our results suggest that the processes of emission of a Type II radio burst occur not only in the upstream region of the shock, i.e. the region that precedes the collision, but also that there must be an emission of the material that has been compressed, as well as of the material that is in the compression region within the structure of the shock itself.
