SH31A:
Approaching Kappa Distributions: Statistical Background, Theoretical Developments, and Applications in Space Plasma Physics I Posters


Session ID#: 8618

Session Description:
Kappa distributions have become increasingly widespread across space plasma physics with the publication rate following, remarkably, an exponential growth. A breakthrough in the field came with the connection of kappa distributions with the solid statistical framework of non-extensive statistical mechanics, a generalization of the classical Boltzmann-Maxwell theory. Thereafter, numerous analyses were developed: Thermodynamics (temperature, pressure, kappa, entropy); positional distribution (when the potential is non-zero); multi-particle distribution, etc. These are followed by a plethora of applications in space plasmas throughout the heliosphere, planetary/cometary magnetospheres, and beyond. We welcome abstracts reporting on the progress of: (i) Theory of kappa distributions and non-extensive statistical mechanics; (ii) Effects of kappa distributions on plasma processes, e.g., linear/nonlinear waves, instabilities, shocks, with emphasis on the Rankine–Hugoniot conditions; (iii) Identification of mechanisms responsible for generating kappa distributions; (iv) Data analyses/ MHD simulations that involve kappa distributions, e.g., particle acceleration, circulation inside planetary magnetospheres, modeling of heliospheric boundaries.
