Implications of X-ray observations for electron acceleration and propagation in solar flares
GD Holman, MJ Aschwanden, H Aurass… - Space science …, 2011 - Springer
High-energy X-rays and γ-rays from solar flares were discovered just over fifty years ago.
Since that time, the standard for the interpretation of spatially integrated flare X-ray spectra at …

A unified computational model for solar and stellar flares
JC Allred, AF Kowalski, M Carlsson - The Astrophysical Journal, 2015 - iopscience.iop.org
We present a unified computational framework that can be used to describe impulsive flares

Physical processes in magnetically driven flares on the sun, stars, and young stellar objects
AO Benz, M Güdel - Annual Review of Astronomy and …, 2010 - annualreviews.org
The first flare on the Sun was observed exactly 150 years ago. During most of the long
history, only secondary effects have been noticed, so flares remained a riddle. Now the …
