The abstract submission deadline is 13 January 2021, 13:00 CET

Session ST1.5 "Turbulence and Waves in Space Plasmas »

Convener: Olga Alexandrova

Co-conveners: Petr Hellinger, Luca Sorriso-Valvo, Julia Stawarz, Daniel Verscharen

The majority of space plasmas are in a turbulent state, displaying fluctuations and non-linear behaviour at a broad range of scales As well as being of fundamental interest, this turbulence may have important effects, such as heating of the solar wind and corona, acceleration of energetic particles, and interaction with magnetic reconnection and shocks. Measurements also suggest the presence of plasma instabilities which may generate quasi-linear waves, such as, e.g., Alfven-Ion-Cyclotron waves at ion scales and whistler waves at electron scales. Many aspects of the turbulence and instabilities are not well understood, in particular, the energy injection mechanism to the cascade, the non-linear turbulent cascade and dissipation mechanisms, non-linear instability saturation mechanisms, and the interaction between instabilities and turbulence. This session will address these questions though discussion of observational, theoretical, numerical, and laboratory work to understand these processes. This session is relevant to many currently operating missions (e.g., Wind, Cluster, MMS, STEREO, THEMIS, Van Allen Probes, DSCOVR) and in particular for Solar Orbiter and Solar Probe Plus.
