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 4861Å~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…
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…
High Resolution Imaging Spectroscopy of a Tiny Sigmoidal Mini-filament Eruption
Jiasheng Wang, Jeongwoo Lee, Jongchul Chae +3
Minifilament (MF) eruption producing small jets and micro-flares is regarded as an important source for coronal heating and the solar wind transients through studies mostly based o…
Tracing Halpha Fibrils through Bayesian Deep Learning
Haodi Jiang, Ju Jing, Jiasheng Wang +5
We present a new deep learning method, dubbed FibrilNet, for tracing chromospheric fibrils in Halpha images of solar observations. Our method consists of a data pre-processing comp…
High-resolution Observations of Small-scale Flux Emergence by GST
Jiasheng Wang, Chang Liu, Wenda Cao +1
Recent observations demonstrated that emerging flux regions, which constitute the early stage of solar active regions, consist of emergence of numerous small-scale magnetic element…
Identifying and Tracking Solar Magnetic Flux Elements with Deep Learning
Haodi Jiang, Jiasheng Wang, Chang Liu +4
Deep learning has drawn a lot of interest in recent years due to its effectiveness in processing big and complex observational data gathered from diverse instruments. Here we propo…
Inferring Vector Magnetic Fields from Stokes Profiles of GST/NIRIS Using a Convolutional Neural Network
Hao Liu, Yan Xu, Jiasheng Wang +4
We propose a new machine learning approach to Stokes inversion based on a convolutional neural network (CNN) and the Milne-Eddington (ME) method. The Stokes measurements used in th…
Evolution of Photospheric Vector Magnetic Field Associated with Moving Flare Ribbons As Seen By GST
Chang Liu, Wenda Cao, Jongchul Chae +7
The photospheric response to solar flares, also known as coronal back reaction, is often observed as sudden flare-induced changes in vector magnetic field and sunspot motions. Howe…
Evolution of Photospheric Flow and Magnetic Fields Associated with The 2015 June 22 M6.5 Flare
Jiasheng Wang, Chang Liu, Na deng +1
The evolution of photospheric flow and magnetic fields before and after flares can provide important information regarding the flare triggering and back reaction processes. However…
Flare differentially rotates sunspot on Sun's surface
Chang Liu, Yan Xu, Wenda Cao +7
Sunspots are concentrations of magnetic field visible on the solar surface (photosphere). It was considered implausible that solar flares, as resulted from magnetic reconnection in…
