| 英文摘要 | Another envelope soliton event below the H+ gyrofrequency and localized density depletion has been discovered in the low auroral region (similar to 1760km) by the Freja satellite. This envelope soliton has a characteristic frequency at similar to 190 Hz, which is also close to the resonance frequency of hydrogen ion-oxygen ion hybrid wave. This event is correlated in time with the observations of the sharp increase of the ratio of oxygen ion density to hydrogen and with the electron energization along the magnetic field. A theoretical model on the ion-ion hybrid wave excited by an energetic electron beam has also been presented. It is found that the ion-ion hybrid wave is mainly excited by the Cherenkov instability in the auroral region. |
