| Zusammenfassung |
| Whistler emissions close to the magnetopause on the magnetospheric
side are investigated using the four Cluster spacecraft. The waves
are found to be generated in thin (electron-scale) sheets moving
with the plasma drift velocity. A feature in the electron data
coincides with the waves; hot magnetospheric electrons disappear for
a few satellite spins. This produces or enhances a temperature
anisotropy, which is found to be responsible for the generation of
the whistler mode waves. The high energy electrons are thought to
be lost through the magnetopause and we suggest that the field
lines, on which the waves are generated, are directly connected to a
reconnection diffusion region at the magnetopause. |
