Abstract: | High temperature phenomena occurring in solar flares are reviewed based on hard X-ray images and spectral analyses of highly ionized iron lines observed aboard the Hinotori spacecraft.Five basic flare components are proposed, i.e., impulsive (I), gradual hard (GH), thermal (T), quasi thermal (QT) and hot thermal (HT) components. A flare shows some combination of the five components. Energy release and transport for each component would give a lot of variety to the hard X-ray image, spectrum and time history of X-rays. |
