摘要
简要回顾利用"日地关系天文台"(Solar Terrestrial Relations Observatory,STEREO)卫星的立体观测资料在日冕物质抛射(Coronal Mass Ejection,CME)研究方面已取得的一些重要进展,主要包括(1)通过极紫外成像仪观测到的日冕极紫外暗化来更准确地估计CME质量,研究CME演化的结构特征;(2)利用STEREO卫星日冕仪的双角度观测,在CME立体传播特征方面取得的新进展;(3)STEREO卫星日球成像仪具有广阔的视场范围,可以跟踪研究CME从太阳表面爆发到形成行星际日冕物质抛射(Interplanetary CME,ICME),及其在内日球层和近地空间的演化特征以及运动特征等。同时,也介绍了利用三角测量技术测定CME特征物理量的新方法。
We briefly review the important observational results for CMEs based on the stereoscopic data by STEREO, including: (1) the study of the structural characteristic of CMEs evolution, by the determination of their mass from the EUV dimming observed by the two EUVI (EUV Imager) telescopes; (2) the study of the propagating characteristic of CMEs in three dimensions, by analyzing the stereo image pairs from the two coronagraphs on board STEREO; (3) the study of the ICMEs as well as their evolution and dynamics through the inner heliosphere to the Earth, by tracking their source regions on the solar surface and the following propagations in the heliosphere from the two HI (Heliospheric Imager) telescopes. Finally, we introduce the new methods for measuring the parameters of
