| Zusammenfassung |
| Solar wind is a turbulent magnetized collisionless plasma. Kolmogorov’s turbulent spectrum
is widely observed at magnetohydrodynamic scales. At smaller scales, i.e. at scales of the
order of the kinetic plasma scales (such as Larmor radii of charged particles or their inertial
lengths, ~ 50Â km for protons and ~ 2Â km for electrons), turbulence is less studied and is a
matter of debate. In this presentation we review different observations related to kinetic
range, such as magnetic spectra, signatures of multi- and mono-fractality, wave
vector anisotropy and indications of different wave modes. Then, we will show new
results related to intermittency and coherent structures present within this range. |
