| Zusammenfassung |
| Early magnetopause observations revealed that the magnetic field can rotate across tangential
current sheets in the form of C-and S-shaped hodograms. We use the four-spacecraft
magnetopause crossings by Cluster in order to study the structure of the C- and S-sheets. We
show that both current sheets can be described by analytical equilibria. We employ a
force-free current sheet equilibrium for description of the C-sheet and develop a new
equilibrium to describe the S-sheet. We suggest that both equilibria be used for
setting up initial conditions in the next generation of current sheet simulations. |
