针状物的数值模拟与形态观测研究进展

Numerical Modeling and Morphological Observation of Solar Spicules

从针状物的数值模拟发展和形态观测进展两大方面,展示针状物近期研究成果。首先,介绍针状物磁流体动力学(magnetohydrodynamics, MHD)数值模拟的内容与进展;然后,介绍日面针状物总量和平均能流密度估算的研究进展;接着,介绍目前较为成熟的日出卫星(Hinode)上太阳光学望远镜(Solar Optical Telescope, SOT)的数据处理方法及观测到的双线和群体运动现象;最后,对目前针状物研究成果和未来研究方向进行总结和展望。

Solar spicules are the fundamental magnetic structures in the chromosphere.To understand the role of spicules in channeling the chromosphere and corona for coronal heating and energy transfer,we introduce the recent development of the spicule studies,including numerical magnetohydrodynamics(MHD)modeling and morphological observations.We highlight the methodology used in the estimation of energy flux by spicules.Based on the data from the Hinode/Solar Optical Telescope,the phenomena of the“two-line”and“group motion”of spicules are analyzed in detail.Finally,we forecast the future studies for spicules.
