Abstract Interplanetary plasma and magnetic field data were measured by the two Helios solar probes from 1974 until 1986 and from 1976 until 1980, respectively, between 0.3 and 1 AU. We used these data to investigate plasma parameters of high-speed streams, especially velocities, densities, and temperatures of protons and α-particles. The possibility is discussed that the variability in these parameters is due to spatial structures which are remnants of the underlying coronal structures (supergranulation cells) preserved in the outflowing solar wind.
Are structures in high-speed streams signatures of coronal fine structures?
