In this study, by simulating the wave‐particle interactions, we show that subrelativistic/
relativistic electron microbursts form the high‐energy tail of pulsating aurora (PsA). Whistler …

Owing to the ever-present solar wind, our vast solar system is full of plasmas. The turbulent
solar wind, together with sporadic solar eruptions, introduces various space plasma …

Pulsating auroras show quasi‐periodic intensity modulations caused by the precipitation of
energetic electrons of the order of tens of keV. It is expected theoretically that not only these …

Van Allen radiation belts consist of relativistic electrons trapped by Earth's magnetic field.
Trapped electrons often drift azimuthally around Earth and display a butterfly pitch angle …

We present observations that provide the strongest evidence yet that discrete whistler mode
chorus packets cause relativistic electron microbursts. On 20 January 2016 near 1944 UT …

We use test particle simulations to model the interaction between radiation belt electrons
and whistler mode chorus waves by focusing on wave amplitude modulations. We quantify …

Chorus waves, discovered as a series of repetitive coherent emissions, are well known for
producing hazard radiation environments in Earth's magnetosphere. Its repetitive nature …

Whistler‐mode extremely low frequency hiss emissions commonly exist in the plasmasphere
and the plasmaspheric plume and contribute to the precipitation loss of the radiation belt …

Abstract High‐Intensity, Long‐Duration, Continuous AE Activity (HILDCAA) events are
studied using long‐term geomagnetic and solar wind/interplanetary databases. We use the …

We investigate the origin of the fine structure of the energy spectrum of precipitating
electrons for the pulsating aurora (PsA) observed by the low‐altitude Reimei satellite. The …
