Impulsive Heating of Solar Flare Ribbons Above 10 MK [PDF]
, 2015 The chromospheric response to the input of flare energy is marked by extended extreme ultraviolet (EUV) ribbons and hard X-ray (HXR) footpoints. These are usually explained as the result of heating and bremsstrahlung emission from accelerated electrons ...
