Anisotropy of Alfvénic turbulence in the solar wind and numerical simulations

Horbury, T. S.; Chen, C. H. K.; Mallet, A. +2 more

We investigate the anisotropy of Alfvénic turbulence in the inertial range of slow solar wind and in both driven and decaying reduced magnetohydrodynamic simulations. A direct comparison is made by measuring the anisotropic second-order structure functions in both data sets. In the solar wind, the perpendicular spectral index of the magnetic field…
