| Zusammenfassung |
| We use whistler waves observed close to the magnetopause as an
instrument to investigate the internal structure of the
magnetopause-magnetosheath boundary layer. We find that this region
is characterized by tube-like structures with dimensions less than
or comparable with an ion inertial length in the direction
perpendicular to the ambient magnetic field. The
tubes are revealed as they constitute regions where whistler waves
are generated and propagate. We believe that the region containing
tube-like structures extend several Earth radii along the
magnetopause in the boundary layer. Within the presumed wave
generating regions we find current structures moving at the whistler
wave group velocity in the same direction as the waves. |
