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…
Magnetic Field Measurements in the Solar Chromosphere Using the H 4861Ã ~Line I: Forward Modeling Based on 1D Models
Jiasheng Wang, Wenxian Li, Xianyong Bai +3
The chromosphere is a complex solar atmosphere that hosts a variety of transients and transports significant free energy to heat the corona. However, due to the limited sensitivity…
Half-year Evolution of a Decaying Solar Active Region and Peripheral Dimming Regions
Jiasheng Wang, Yu Xu, Zhengyong Hou
Using multi-wavelength observations from the Solar Dynamics Observatory (SDO), we investigated the six-month decay process of the solar active region NOAA AR 12738 from April to Oc…
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…
