Subproton-scale turbulence in astrophysical plasmas

June 17, 2013



Abstract: Recent observations of the solar wind plasma, and the results of high-resolution numerical simulations revealed the presence of significant magnetic, density, and electric fluctuations at scales smaller than ion gyroscale, often referred to as dispersion or dissipation scales. We discuss subproton plasma turbulence in astrophysical plasmas, specifically concentrating on the role of kinetic-Alfven and whistler modes and revealing their common characteristics as well as essential physical differences. The results are useful for formulation of phenomenological models and interpretation of observational data.
