Uncovering the heterogeneity of a solar flare mechanism with mixture models
Frontiers in Astronomy and Space SciencesThe physics of solar flares occurring on the Sun is highly complex and far from fully understood. However, observations show that solar eruptions are associated with the intense kilogauss fields of active regions, where free energies are stored with ...

The Astrophysical Journal LettersAbstract This Letter proposes that the ion temperature is several times the local electron temperature in the hot onset phase and in the above-the-loop region of solar flares. The Letter considers: the evidence of spectral line Doppler widths (“nonthermal” broadening); evidence for “universal” ion and electron temperature increase ...

Can Solar Limb Flare Prediction Be Properly Made by Extreme-ultraviolet Intensities?
The Astrophysical Journal LettersWe address the question of whether the solar limb flare prediction can be properly made by EUV intensity, which has less projection effects than solar white light and magnetogram data.
