Solar flare line broadening in hot onset and above-the-loop plasma may come largely from ions heated to about 60 MK, several times the electron temperature.

In three solar flares, the low-energy cutoff of nonthermal electrons shows a high-low-high time profile around hard X-ray peaks, while the total injected electron rate shows the opposite pattern.
During a long X-class flare, Fe XXI spectra reveal nonthermal plasma motions up to 130 km/s that persist for hours above the loop tops and may slow the cooling of hot flare plasma.
Numerical MHD and test-particle simulations indicate that unsteady loop-top dynamics enhance electron acceleration efficiency compared to quasi-steady cases by mitigating betatron cooling at compressed field edges.
3D MHD modeling of candle-flame solar flares reveals Y-points do not coincide with apparent cusp tips and observed downflow speeds underestimate reconnection Alfvén speeds by 2-10x.
