Fast acceleration of "killer" electrons and energetic ions by interplanetary shock stimulated ULF waves in the inner magnetosphere
Zong, QuiGang; Wang, YongFu; Yang, Biao +3 more
Energetic electrons and ions in the Van Allen radiation belt are the number one space weather threat. Understanding how these energetic particles are accelerated within the Van Allen radiation belt is one of the major challenges in space physics. This paper reviews the recent progress on the fast acceleration of "killer" electrons and energetic io…
Electron dynamics in collisionless magnetic reconnection
Wang, Shui; Huang, Can; Lu, San +3 more
Magnetic reconnection provides a physical mechanism for fast energy conversion from magnetic energy to plasma kinetic energy. It is closely associated with many explosive phenomena in space plasma, usually collisionless in character. For this reason, researchers have become more interested in collisionless magnetic reconnection. In this paper, the…
High-speed flowing plasmas in the Earth's plasma sheet
Parks, George; Fu, SuiYan; Sun, WeiJie +4 more
A research topic of great interest to the space physics community is the observation of plasmas flowing at hundreds of kilometers per second in the Earth's plasma sheet. Although considerable effort has been made to understand the source of fast-flowing plasmas, many questions remain unanswered about the mechanisms that produce high-speed flows an…
Electromagnetic ion-cyclotron instability driven by combined loss-cone and temperature anisotropy distribution of suprathermal ions
Hua, YuePing; Wu, DeJin; Wang, DeYu
Electromagnetic ion cyclotron (EMIC) waves, particularly their generation and excitation mechanisms, have been a subject of wide interest because of their potential importance in ion acceleration and heating. In this work, the parameter-dependence of EMIC instabilities is investigated with a combined loss-cone and temperature anisotropy distributi…
