| Zusammenfassung |
| We study the polarization status of magnetic field fluctuations at proton scales looking for
possible links between the large-scale and small-scale features of solar wind fluctuations
across the frequency break separating fluid and kinetic regimes. The main goal is to correlate
the occurrence of proton temperature anisotropy, low proton β∥ values and, magnetic field
fluctuations polarization to the particular state of turbulence found within the inertial range.
We found clear correlations between each type of polarization, either left or right, and
turbulence status. Moreover, for the first time in literature, we show that left-handed and right
handed polarized fluctuations occupy different areas of the temperature anisotropy-β∥
plot, as expected for Alfvén Ion Cyclotron and Kinetic Alfvén waves, respectively. |
