【摘要】：人类第一次注意到太阳大气中发生的喷流现象,是在20世纪20年代的Mt.Wilson观测台站发现的Hα冲浪。尽管已经过去了接近一个世纪,由于喷流本身并没有表现出像太阳耀斑那样的耀眼增亮,也没有像日冕物质抛射那样能够直接影响到近地空间环境,太阳大气喷流一直没能引起人们足够的重视。然而,近些年的一些研究进展表明,喷流不仅在分析太阳磁场拓扑结构和演化、与磁流体力学波(如类阿尔芬波)的相互作用、加热局地日冕以及加速太阳风等方面可能起着十分重要的作用,也与耀斑、日冕物质抛射等太阳上的极端爆发活动有着密切的关系。文章首先简要回顾太阳大气喷流的理论和观测成果,然后介绍作者在喷流触发高速日冕物质抛射方面最新的研究成果。最后简述喷流研究中亟待解决的一些问题和未来的研究方向。
[Abstract]:For the first time, the phenomenon of jet in the solar atmosphere was observed at the Mt.Wilson observation station in the 1920s. Although nearly a century has passed, since the jet itself does not exhibit the dazzling brightness of solar flares, nor does it have a direct impact on the near-Earth space environment, as is the coronal mass ejection. The solar atmospheric jet has not been paid enough attention to. However, recent advances have shown that the jet not only analyses the topological structure and evolution of the solar magnetic field, but also interacts with magnetohydrodynamic waves, such as Alfen-like waves, Heating the local corona and accelerating the solar wind may play a very important role in the solar extreme eruptions such as flares coronal mass ejections and so on. This paper first briefly reviews the theoretical and observational results of solar atmospheric jet, and then introduces the author's latest research results in triggering high speed coronal mass ejection. Finally, some problems to be solved in jet research and the future research direction are briefly described.
