Abstract
A physical mechanism to produce pulsating aurora (PsA) has been considered to be the interaction of the electron and the chorus wave generated near the equatorial plane of the magnetosphere. A recent observation of high temporal resoluti...

Abstract
A specialized ground‐based system has been developed for simultaneous observations of pulsating aurora (PsA) and related magnetospheric phenomena with the Arase satellite. The instrument suite is composed of (a) six 100 Hz sampling high‐...

This study explores the impact of the exosphere hydrogen (H) density on the ionosphere-plasmasphere system using a model whose key inputs are constrained by ionosphere observations at both ends of the magnetic field line with an L-value of 1.75 in...

We found that the solar panel output current of JAXA's Venus explorer Akatsuki is below values expected from percentage of shadow during penumbras. We also found that a similar phenomenon occurs in JAXA's Van Allen radiation belts explorer Arase d...
