Comparison of Helium Abundance between ICMEs and Solar Wind near 1 AU
Hongqiang Song, Xin Cheng, Leping Li +2
The Helium abundance, defined as , is 8.5 in the photosphere and seldom exceeds 5 in fast solar wind. Previous statistics have demonstrated tha…
Compound eruptions of twin flux ropes in a solar active region
Ruisheng Zheng, Liang Zhang, Bing Wang +6
Compound eruptions represent that multiple closely spaced magnetic structures erupt consecutively within a short interval, and then lead to a single flare and a single CME. However…
Formation of a solar filament by magnetic reconnection and coronal condensation
Leping Li, Hardi Peter, Lakshmi Pradeep Chitta +1
In solar filament formation mechanisms, magnetic reconnection between two sets of sheared arcades forms helical structures of the filament with numerous magnetic dips, and cooling…
The Inhomogeneity of Composition along the Magnetic Cloud Axis
Hongqiang Song, Qiang Hu, Xin Cheng +6
It is generally accepted that CMEs result from eruptions of magnetic flux ropes, which are dubbed as magnetic clouds in interplanetary space. The composition (including the ionic c…
Solar Cycle Dependence of ICME Composition
Hongqiang Song, Leping Li, Yanyan Sun +3
Coronal mass ejections (CMEs) are one of the most energetic explosions in the solar atmosphere, and their occurrence rates exhibit obvious solar cycle dependence with more events t…
On-disk solar coronal condensations facilitated by magnetic reconnection between open and closed magnetic structures
Leping Li, Hardi Peter, Lakshmi Pradeep Chitta +1
Coronal condensation and rain are a crucial part of the mass cycle between the corona and chromosphere. In some cases, condensation and subsequent rain originate in the magnetic di…
