The frequency spectrum of the solar-wind magnetic-field fluctuations that reside outside the strong current sheets: fast and slow solar wind

Motivated by knowledge that directional discontinuities (strong current sheets) in the solar-wind magnetic time series have dominating effects on the magnetic power spectral density of the solar wind, ...
