SH21C:
The Forefront of Kappa Distributions: Understanding Plasma Processes in the Heliosphere and Kolmogorov in Space—Application and Extension of Turbulence Theory in Space Plasmas Posters


Submit an Abstract to this Session


Session ID#: 61019

Session Description:
Space plasmas are often collisionless and correlated particle systems characterized by a non-Maxwellian behavior, typically described by the formulations of kappa distributions. These distributions were first widely used to model both the “core” and “tail” features of the observed distributions. Recent developments explain the origin of kappa distributions through statistical mechanics and thermodynamics, revealing the robust physical meaning of temperature, kappa index, thermal pressure, entropy, and other thermodynamic parameters that characterize space plasma properties and processes.

More than fifty years after the earliest observations of powerlaw magnetic spectra in the solar wind, hydrodynamic turbulence theories emanating from the pioneering works of Taylor, von Karman, Kolmogorov, Oubukov and others, have been applied and extended in many ways. This activity extends into corona, solar wind, magnetosheric, planetary and astrophysical applications. With the advent of high resolution and multispacecraft instrumentation, turbulence concepts have probed deeply into the realm of kinetic plasma phenomena.
