WebMay 20, 2016 · The chromospheric evaporation in the Fe xxi line observed by the IRIS instrument shows a gradual increase of the blueshift velocities during the early flare phase. This increase can be at least partially explained by the changing geometry of flare loops at the position of the IRIS slit as a result of the slipping reconnection.

WebJan 15, 2024 · There are two types of chromospheric evaporation. For the explosive evaporation, the emission lines formed in the corona are blueshifted, while the emission lines formed in the transition region and chromosphere are redshifted (e.g., Czaykowska et al. 1999; Brosius & Phillips 2004; Milligan & Dennis 2009; Brosius 2013; Li et al. 2015 ).
