An overview of STEREO/WAVES science results

Abstract

Summary form only given. The Radio and Plasma Wave (WAVES) Experiment on the Solar Terrestrial Relations Observatory (STEREO) mission has been tracking heliospheric radio signatures of large-scale energy release on the Sun in the form of radio bursts at frequencies below the ionospheric cutoff. In particular, type III bursts caused by beams of electrons propagating along open magnetic field lines and type II bursts caused by electrons accelerated at shocks driven by coronal mass ejections (CMEs). Occasionally one observes type IV bursts, which are thought to be produced by energetic electrons trapped in flare magnetic structures. In addition, STEREO/WAVES observations provide information on radio enhancement associated with colliding CMEs within the coronagraphic field of view. Most of these radio emissions were also observed by the WAVES experiment on board the Wind spacecraft, but the STEREO/WAVES experiment provides additional information because of the stereoscopic observations. This paper summarizes some of the key results obtained using the STEREO/WAVES observations.
