Le séminaire a lieu le jeudi 22 septembre 2005 de 11h00
à
12h00
dans la salle de réunion
du PHC (Observatoire de Nice).
The anisotropy of magnetophydrodynamic turbulence is investigated by
using data from the solar wind by the Helios 2 satellite. We investigate
the behaviour of the complete high-order moment tensors of magnetic
field increments and we compare the usual longitudinal structure
functions which have mixed contributions, namely isotropic plus
anisotropic, with the fully anisotropic contribution. We discuss the
radial dependence of anisotropy and intermittency, and the different
types of wind.
