Interplanetary Shocks between 0.3 and 1.0 au: Helios 1 and 2 Observations

The Helios 1 (H1) and Helios 2 (H2) spacecraft measured the solar winds at a distance between ∼0.3 and 1.0 au from the Sun. With increasing heliocentric distance ( r _h ), the plasma speed is found to increase at ∼34–40 km s ^−1 au ^−1 and the density exhibits a sharper fall ( ${{r}_{{\rm{h}}}}^{-2}...
