Universality of Solar-Wind Turbulent Spectrum from MHD to Electron Scales
Universality of Solar-Wind Turbulent Spectrum from MHD to Electron Scales
To investigate the universality of magnetic turbulence in space plasmas, we analyze seven time periods in the free solar wind under different plasma conditions. Three instruments on Cluster spacecraft operating in different frequency ranges give us the possibility to resolve spectra up to 300 Hz. We show that the spectra …
