Intense but Harmless: Exo-Space Weather Around an M Dwarf with a Single-Hemisphere Dynamo
Zheng Sun, Julián D. Alvarado-Gómez, Hui Tian +4
M dwarfs are among the most promising host stars in the search for habitable exoplanets. However, their active atmospheres drive intense magnetic activity, including energetic flar…
How Magnetic Field Strength Affects Stellar Coronal Mass Ejection Dynamics
Zheng Sun, Julián D. Alvarado-Gómez, Hui Tian
Observations show that stellar coronal mass ejection (CME) candidates display relatively lower kinetic energies compared to expectations from solar flare-CME relations extrapolated…
Fine-scale downflows above flare ribbons captured by Solar Orbiter/EUI
Zheng Sun, Alexander G. M. Pietrow, Malcolm K. Druett +8
In solar flares, flare ribbons map chromospheric footpoints where flare energy deposition occurs. These locations are associated with field aligned energy transport from the corona…
Fine Structure and Formation Mechanism of a Sunspot Bipolar Light Bridge in NOAA AR 13663
Fangfang Qiao, Hao Li, Jiasheng Wang +3
Bipolar Light Bridges (BLBs) are bright regions located between sunspot umbrae of opposite magnetic polarity. They are typically characterized by strong magnetic fields and intense…
Resolving Interchange Reconnection Dynamics in a Fan-Spine-like Topology Observed by Solar Orbiter
Yadan Duan, Xiaoli Yan, Junchao Hong +5
Interchange reconnection is believed to play a significant role in the production of solar jets and solar wind. However, the dynamics of interchange reconnection in the low corona…
The Detectability of Coronal Mass Ejections in the Low Corona Using Multi-slit Extreme-ultraviolet Spectroscopy
Lami Chan, Xianyong Bai, Hui Tian +6
The spectra of coronal mass ejections (CMEs) in the low corona play a crucial role in understanding their origins and physical mechanism, and enhancing space weather forecasting. H…
Ubiquitous Small-scale EUV Upflow-Like Events above Network Regions Observed by the Solar Orbiter/Extreme Ultraviolet Imager
Yadan Duan, Hechao Chen, Zhenyong Hou +2
Universal small-scale solar activity in quiet region are suggested to be a potential source of solar wind and the upper solar atmosphere. Here, with the high-resoltion 174 Å~imagin…
An Extreme Stellar Prominence Eruption Observed by LAMOST Time-Domain Spectroscopy
Lu Hong-Peng, Tian Hui, Zhang Li-Yun +6
We report the detection of an extreme stellar prominence eruption on the M dwarf LAMOST J044431.62+235627.9, observed through time-domain H spectroscopy with the Large Sky Area…
Fast Downflows Observed during a Polar Crown Filament Eruption
Zheng Sun, Hui Tian, Ting Li +2
Solar filaments can undergo eruptions and result in the formation of coronal mass ejections (CMEs), which could significantly impact planetary space environments. Observations of e…
Three types of solar coronal rain during magnetic reconnection between open and closed magnetic structures
Fangfang Qiao, Leping Li, Hui Tian +4
Coronal rain (CR) is a crucial part of the mass cycle between the corona and chromosphere. It includes the flare-driven CR and two types of quiescent CR separately along the non-fl…
The Solar Origin of an Intense Geomagnetic Storm on 2023 December 1st: Successive Slipping and Eruption of Multiple Magnetic Flux Ropes
Zheng Sun, Ting Li, Yijun Hou +12
The solar eruption that occurred on 2023 November 28 (SOL2023-11-28) triggered an intense geomagnetic storm on Earth on 2023 December 1. The associated Earth's auroras manifested a…
Is it possible to detect coronal mass ejections on solar-type stars through extreme-ultraviolet spectral observations?
Zihao Yang, Hui Tian, Yingjie Zhu +3
Stellar coronal mass ejections (CMEs) from host stars are an important factor that affects the habitability of exoplanets. Although their solar counterparts have been well observed…
Formation of Fan-spine Magnetic Topology through Flux Emergence and Subsequent Jet Production
Yadan Duan, Hui Tian, Hechao Chen +4
Fan-spine magnetic structure, as a fundamental three-dimensional topology in magnetic reconnection theory, plays a crucial role in producing solar jets. However, how fan-spine conf…
Observation of two splitting processes in a partial filament eruption on the sun: the role of breakout reconnection
Zheng Sun, Ting Li, Hui Tian +5
Partial filament eruptions have often been observed, however, the physical mechanisms that lead to filament splitting are not yet fully understood. In this study, we present a uniq…
