Numerical Simulations of Kinetic Alf ´v en Waves to Study Spectral Index in Solar Wind Turbulence and Particle Heating
Kinetic Alfv´ en wave filamentation solar wind spectral index chaotic structure
2010/9/16
We present numerical simulations of the modified nonlinear Schr¨odinger equation satisfied by kinetic Alfv´en waves (KAWs) leading to the formation of magnetic filaments at different times. The ...
Parallel and perpendicular cascades in solar wind turbulence
Parallel and perpendicular cascades solar wind turbulence
2009/11/9
MHD-scale fluctuations in the velocity, magnetic, and density fields of the solar wind are routinely observed. The evolution of these fluctuations, as they are transported radially outwards by the sol...

nonextensive entropy path probability distributions solar wind turbulence
2009/11/9
The observed scale dependence of the probability distributions of the differences of characteristic solar wind variables is analyzed. Intermittency of the turbulent fluctuations at small-scale spatial...
