Visualization of regions of electromagnetic wave-plasma interactions surrounding the Earth

Researchers have investigated wave-particle interactions between energetic electrons and chorus waves evolving in the space surrounding the Earth using the scientific satellite Arase and, simultaneously, transient auroral flashes by the ground-based global observation network. The investigation visualized asymmetric spatial development of wave-particle interaction regions on the order of sub-seconds. This is expected to contribute to the safe and secure exploration of space by establishing hazar...
