Session ID#: 15769

Session Description:
Most of the visible universe is hot magnetized plasma in a turbulent state. Heating and acceleration of such plasma can be due to dissipation of turbulent fluctuations occurring at kinetic scales. It is therefore crucial to understand the underlying physical mechanism related to energy dissipation and particle energization. This session will focus on such processes at kinetic scales from the point of view of theory, numerical simulations, and spacecraft observations. We solicit contributions addressing fundamental questions regarding heating and acceleration mechanisms by turbulent fluctuations, energy partition among different particle species and in different energy ranges. How do such processes operate in different turbulent environments such as the pristine solar wind, shocks and associated sheath regions and flow interaction regions?  Theoretical and observational studies relating to recent spacecraft measurements in near earth space (Cluster, THEMIS and MMS) planetary magnetospheres (Cassini, MAVEN) and future mission concepts such as THOR are particularly welcome.
