| Zusammenfassung |
| Magnetic reconnection is a fundamental mechanism of energy dissipation and
particle energization in space plasma. Spacecraft observations and
numerical studies have established that it occurs in small-scale
intermittent structures such as thin current sheets that form
spontaneously in turbulent plasma. This kind of turbulent reconnection
leads to significant particle heating and acceleration as well as to the
dissipation of turbulent energy at kinetic scales. However, the extent of
its contribution to turbulent dissipation has yet to be determined.
Here we present results from in situ observations made by MMS and CLUSTER
in the Earth's magnetosheath. A statistical study of a large number of
thin current sheets allows us to establilsh their importance for
dissipation while the in-depth study of reconnecting current sheets yields
valuable insight into the exact mechanisms of particle heating and
acceleration. |
