| Zusammenfassung |
| Numerical simulations reveal various nonstationary processes in collisionless quasi-perpendicular shocks such as shock front oscillations, self-reformation, generation of ion-scale ripples and emission of oblique whistler waves. These phenomena and their relationship/competition are not fully understood, particularly since they have mostly been studied in the context of 1-D or 2-D simulations of strictly perpendicular shocks. We present the results of a comparative analysis of 2-D and 3-D hybrid simulations showing in detail the spatio-temporal properties of the different processes. In particular, we investigate the parameter dependencies of the various processes on the Mach number, shock angle and proton beta. |
