WebApr 11, 2024 · One is based on the evaporation process during the flare, which can transport the chromospheric fractionated plasma very quickly to the corona in the decay phase of the flares. The other scenario is based on the evaporation process as well as the flare-driven Alfvén waves. In the decay phase, the reflection of the high amplitude flare … WebMay 12, 2024 · Solar flares are impulsive events with energies reaching up to 10 32 erg, caused by the sudden release of free magnetic energy in the corona that is transported into the chromosphere during the impulsive phase of the flare event. The prevailing theory is that this energy transport arises from a propagating beam of accelerated particles driven from …

In this topical review I revisit the ``chromospheric flare''. … WebRed-shifted emission streaks of Hα line are found at the initial phase of almost all flares which occur near the disk center, and are considered to be substantial features of the red asymmetry. It is found that a downward motion in the flare chromospheric region is the cause of the red-shifted emission streak. port sudan shipchandler
