Solar Flare Ion Temperatures

open access: yesThe Astrophysical Journal Letters
Abstract 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?

open access: yesThe Astrophysical Journal Letters
We 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.

Dynamics of the Coronal Magnetic Field in the 2022 October 2 X-class Flare

open access: yesThe Astrophysical Journal
Solar flares are driven by the release of free magnetic energy and are often associated with the restructurization of the magnetic field topology. Yet, observations of the evolving magnetic field in the flaring volume are limited to very few cases ...
