摘要
太阳风中的电磁离子回旋(Electromagnetic Ion Cyclotron,EMIC)波自报道以来,受到了广泛的关注和研究.由于波的频率接近质子的回旋频率,EMIC波可以通过回旋共振波粒相互作用将波能传递给离子,并在太阳风粒子加热和加速等能化现象中发挥重要作用.总结了太阳风中EMIC波的观测和理论研究进展,包括EMIC波在磁云内外、磁云和行星际日冕物质抛射鞘区中的观测研究得到的一系列结果以及基于观测进行波的激发机制所取得的研究进展,并展望未来研究太阳风中EMIC波的突破方向.
Electromagnetic Ion Cyclotron(EMIC)waves in the solar wind have received much attention since they were discovered.EMIC waves are important in the plasma heating and acceleration in the solar wind because they can effectively transfer wave energy to ions via the cyclotron resonance.This paper summarizes the progress of EMIC waves observation and theoretical research in the solar wind,including a series of results obtained from EMIC waves observation in and out of magnetic clouds,Interplanetary Coronal Mass Ejections(ICMEs)sheath region,and the research progress for excitation mechanism of EMIC waves based on observations.Finally,the potential research of EMIC waves in the solar wind in the future is anticipated.
