Investigation on the Relation between Active Regions' Compliance with Empirical Laws and Flare Productivity
Jinhui Pan, Rui Liu, Jiangtao Su +1
It remains evasive whether solar active regions (ARs) obeying or violating Hale's polarity law, Joy's tilt law, and the hemispheric helicity rule (HHR) differ in flare productivity…
Height and Energy Evolution of X-ray Double Sources in a Solar Flare
Hanya Pan, Astrid M. Veronig, Rui Liu
In the standard model, magnetic reconnection at a vertical current sheet above the flare arcade is key to explaining many aspects of solar eruptions. The supra-arcade region is whe…
Investigation on the Predictive Potentiality of Photospheric Magnetic Parameters for Distinguishing Confined from Eruptive Solar Flares
Jinhui Pan, Rui Liu
A question often arises as to why some solar flares are confined in the lower corona while others, termed eruptive flares, are associated with coronal mass ejections (CMEs). Here w…
SARD: A YOLOv8-Based System for Solar Active Region Detection with SDO/HMI Magnetograms
Jinhui Pan, Jiajia Liu, Shaofeng Fang +1
Solar active regions are where sunspots are located and photospheric magnetic fluxes are concentrated, therefore being the sources of energetic eruptions in the solar atmosphere. T…
Waiting Time Distribution of Supra-Arcade Downflows
Zichao Yang, Rui Liu
Supra-arcade downflows (SADs) are dark, sunward-moving structures above the arcade of flare loops. Naturally they are considered to be associated with outflows resulting from magne…
