Repeated Sunspot Light Bridge Jets Associated with Slipping Base Brightenings

Yadan Duan, Xiaoli Yan, Yuhang Gao +3

Light bridge (LB) jets offer a unique window into small-scale eruptive phenomena within sunspots, the Sun's strongest magnetic environments; however, their generation mechanism rem…

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…

Reconnection nanojets in an erupting solar filament with unprecedented high speeds

Yuhang Gao, Hui Tian, David Berghmans +4

Solar nanojets are small-scale jets generated by component magnetic reconnection, characterized by collimated plasma motion perpendicular to the reconnecting magnetic field lines.…

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 Ã ~imagi…
