Most heliospheric plasmas are collisionless, so that waves produced by plasma instabilities provide the necessary interactions to transfer energy and momentum to the particles. A new and emerging field is the study of the development and evolution of nonlinear plasma waves and turbulence.
The recently launched THEMIS and STEREO missions, as well as Cluster and Double Star have provided valuable data on wave particle interaction processes in various crucial regions of the magnetosphere and in the solar wind. These missions have covered a wide range of wave spatial and temporal scales.
This session will provide the opportunity to report on the latest results regarding the study of basic plasma processes such as particle acceleration, radiation generation, magnetic reconnection, substorm onsets, and characteristics of Alfvénic and solitary structure turbulence .. Special emphasis will be focused on the connection between small-scale processes and large-scale phenomena. We solicit contributions on new results associated with plasma wave modes, wave-particle interactions (both linear and nonlinear) and the development of turbulence in space plasmas. Theory, simulation and data analyses are welcome.
