A Special Kind of Interplanetary Coronal Mass Ejection

Zhao, G. Q.; Zhao, Y.; Li, H. B. +3 more

It is generally believed that coronal mass ejections (CMEs) have magnetic flux rope structures because of their helical shapes. However, only about 30%–40% of interplanetary CMEs (ICMEs) have a local magnetic flux rope structure. The usual explanations are that the spacecraft only crossed the flank of the ropes and failed to detect the complete ma…

Interpretation of the coronal magnetic field configuration of the Sun

Li, Xing; Li, Bo; Yu, Hui

The origin of the heliospheric magnetic flux on the Sun, and hence the origin of the solar wind, is a topic of hot debate. While the prevailing view is that the solar wind originates from outside the coronal streamer helmets, there also exists the suggestion that the open magnetic field spans a far wider region. Without the definitive measurement …
