| Abstract: |
Solar flares are very spectacular and exhibit a variety of plasma
motions. As a flare evolves, flare loops show many dynamic features,
such as plasma heating and cooling, chromospheric evaporation,
reconnection inflows and outflows, and so on. In addition, many
ejection phenomena, such as filament/prominence eruptions, have been
observed in chromospheric lines, in the extreme ultraviolet (EUV), and
in X-rays. Flare-associated waves and the related plasma motions have
also been studied. These plasma motions can be observed as phenomena
accompanied by Doppler shifts in spectroscopic observations.
Therefore, spectroscopic observations are crucially important for
understanding the dynamics of flare plasma. Moreover, with
multi-wavelength observations, we synergistically understand the flare
physics morphologically, qualitatively, and quantitatively. We
overview recent observations of solar flares, particularly those
obtained by Hinode, STEREO, and SDO, and show (only a small part
of) the dynamic features of flare plasma. |
