Observations of Langmuir Waves Associated with Type III Radio Bursts : Wind Observations and Further Improvements with Inner Heliospheric Missions
Abstract
Interplanetary electron beams, produced by solar flares or CMEs, are unstable in the solar wind and generate Langmuir waves at the local plasma frequency Fp. These waves are then converted into the so-called Type III radio bursts which are freely propagating electromagnetic emissions at Fp or its harmonic. We present a statistical analysis of both in-situ Langmuir Waves, associated energetic electrons and Type III bursts recorded simultaneously by the WIND spacecraft. We discuss the relevance of these observations with respect to the latest developments of Type III generation theories. Finally we describe the possible improvements that the forthcoming inner heliospheric mission can bring to this topic.
