Instabilities and Their Role in Modifying Plasma Dynamics

Session ID#: 75936

Session Description:
Plasma throughout the heliosphere is subject to a large variety of instabilities driven by processes ranging from differential flows and temperature anisotropies to large amplitude waves. While the temperature anisotropy and drift-driven instabilities are often invoked when discussing the global evolution of plasmas such as the solar wind, these instabilities can also have a dramatic effect on the local dynamics of the plasma, modifying momentum transport and heating, and efficiently scattering particles. In this session, we hope to examine the interplay between instabilities and other fundamental plasma processes at work in the heliosphere, such as turbulence, reconnection, and shocks, through the use of observational data and numerical simulations. This interplay is particularly timely due to the availability of low-beta, near-Sun plasma data from Parker Solar Probe and high resolution and cadence field and particle data from the Magnetospheric Multiscale mission.
