| Zusammenfassung |
| Large compressions of the magnetopause are proposed to occasionally result
from temporary encounters of the magnetosphere with dust streams in
interplanetary space. Such streams may have their origin in cometary dust
tails or asteroids which cross the inner heliosphere or in meteoroids in
Earth's vicinity. Dust ejected from such objects when embedding the
magnetosphere for their limited transition time should cause substantial
global deformations of the magnetopause/magnetosphere due to the very large
dust grain mass and momentum which compensates for the low dust density when
contributing to the upstream pressure variation. |
