AB: Growing pool of in-situ data on collisionless shocks in solar wind plasmas strongly suggests a comparative analysis of the data with largely hypothetical models of astrophysical shocks, e.g. galactic Supernova cosmic ray shocks. Despite tremendous difference in the energy content the scaling parameters when applied in high-beta limit (at least in downstream) shows a remarkable analogy of plasma turbulence and particle acceleration processes in both limits. Thus solar wind case study may serve as a valuable testbed to validate the astrophysical models.
