Outline of Final Research Achievements

The inner magnetosphere, that is, the near-Earth space where the weather satellite "Himawari" and the GPS satellites are flying, is filled with plasma consisting of charged particles. The dominant component of plasma in the inner magnetosphere is proton during ordinary times, whereas it becomes O+ ion once geomagnetic storms occur. In this study, we investigated the cause of the ion composition change, using data obtained by scientific satellites surveying the inner magnetosphere. It was found that O+ ions are directly flowing into the inner magnetosphere and they are accelerated locally and selectively by electromagnetic field disturbances accompanying with magnetic field dipolarization.
