1. Cluster investigations of the extent and altitude distribution of the auroral density cavity
Sammanfattning : The auroral density cavity constitutes the boundary between the cold, dense ionospheric plasma and the hot, tenuous plasma sheet plasma. The auroral density cavity is characterized by low electron density and particle populations modified by parallel electric fields. LÄS MER
2. Cluster multi-point observations of the auroral acceleration region
Sammanfattning : .... LÄS MER
3. Multi-Spacecraft Observations of the Auroral Acceleration Region
Sammanfattning : The two major agents for producing aurora are generally believed to be the quasi-static parallel electric fields, accelerating electrons in the auroral acceleration region (AAR), and Alfvén waves. The Cluster spacecraft quartet has made multi-spacecraft measurements in the AAR possible for the first time. LÄS MER
