摘要:

我们研究了2000年3月5日观测到的日冕物质抛射(CME)中不同波动现象之间的关系。在195 ° C的EIT记录图像中观察到EIT波。LASCO/C2的白光图像显示了清晰的偏转和扭结的传播以及CME。由Utron记录的光谱观测揭示了两条O { \sc{vi} }线(1032和1037 nm)的过度线加宽。此外,观察到非常热的线,例如Si { \sc{xii} }和Mg { \sc{x} }。有趣的是,EIT波、流光偏转和沿狭缝的强度调制都是向东北方向传播的。空间和时间的相关性表明,流光偏转和谱线加宽很可能是由于日冕物质抛射驱动的冲击波和EIT波是一个日冕物质抛射驱动的冲击波在较低的日冕签名。

英文摘要:

We study the relationship between different wave phenomena associated with a coronal mass ejection (CME) observed on 05 Mar. 2000. EIT waves were observed in the images recorded by EIT at 195 Å. The white-light LASCO/C2 images show clear deflection and propagation of a kink along with the CME. Spectroscopic observations recorded by the UVCS reveals excessive line broadening in the two O {\sc{vi}} lines (1032 and 1037 Å). Moreover very hot lines such as Si {\sc{xii}} and Mg {\sc{x}} were observed. Interestingly, the EIT wave, the streamer deflection and the intensity modulation along the slit were all propagating North-East. Spatial and temporal correlations show that the streamer deflection and spectral line broadening are highly likely to be due to a CME-driven shock wave and that the EIT wave is the signature of a CME-driven shock wave in the lower corona.
