Evolution of coronal mass ejections through the heliosphere

(cont.) These findings impose a serious problem on particle heating and acceleration within ICMEs. Both case studies and superposed epoch analysis demonstrate that plasma depletion layers (PDLs) and mirror-mode waves occur in the sheath regions of ICMEs with preceding shocks. A theoretical analysis shows that shock-induced temperature anisotropies can account for many observations made in interplanetary shocks, planetary bow shocks and the termination shock in the heliosphere. A comparative study of these shocks and corresponding sheaths reveals some universal processes, such as temperature anisotropy instabilities, magnetic field draping and plasma depletion. These results underscore important physical processes which alter the ICME environment.
