Non-linear evolution of unstable acoustic waves in cosmic ray modified shocks

Show Summary Details

Preview

The non-linear evolution of unstable acoustic waves in the precursors of cosmic ray mediated shocks with large Mach numbers results in the formation of a host of weak shock waves. These weak shocks heat the thermal plasma, and therefore change the parameters of the strong large-scale shock.
