Limb Shift of the Fe I 6569 Ã line on the Sun
H. C. Yu, M. D. Ding, J. Hong +2
The convective motions of solar granules generate a center-to-limb variation of Doppler velocity in the photospheric lines, known as the limb shift effect. This study presents a co…
Data-constrained Magnetohydrodynamic Simulation of a Filament Eruption in a Decaying Active Region 13079 on a Global Scale
Yihua Li, Yang Guo, Jinhan Guo +3
Filaments are special plasma phenomena embedded in the solar atmosphere, characterized by unique thermodynamic properties and magnetic structures. Magnetohydrodynamic (MHD) simulat…
Investigating an Erupting Metric-decimetric Radio Depression and its Physical Origin
B. T. Wang, X. Cheng, J. Y. Yan +8
We present direct metric-decimetric radio imaging observations of a fascinating quiescent filament eruption on 2024 March 17 using data from the DAocheng Radio Telescope (DART), wi…
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…
