Chromospheric evaporation
WebNov 26, 2024 · The impulsive 100-fold increase in the X-ray flux over the quiescent background occurs as the result of chromospheric evaporation filling the coronal loops with high-temperature, high-emission ... WebAbstract. Chromospheric evaporation is currently the most popular theory for explaining the source of the coronal flare material and the upward motions of X-ray emitting material observed as soft X-ray line broadenings and line shifts at the start of solar flares.
