Statistics of Solar Filament Mass based on CHASE Sun-as-a-star Spectroscopic Observations
T. Y. Xie, Z. H. Zhao, X. Cheng +5
Filaments are cool and dense plasmas suspended in the hot corona of the Sun and other stars. Accurately estimating their masses is of great significance for understanding subsequen…

Data-constrained 3D MHD Simulation of a Spiral Jet Caused by an Unstable Flux Rope Embedded in Fan-spine Configuration
Z. F. Li, J. H. Guo, X. Cheng +5
Spiral jets are impulsive plasma ejections that typically show an apparent rotation motion. Their generation, however, is still nont understood thoroughly. Based on a high-resoluti…
