Chromospheric evaporation
WebAbstract. Chromospheric evaporation is currently the most popular theory for explaining the source of the coronal flare material and the upward motions of X-ray emitting material observed as soft X-ray line broadenings and line shifts at the start of solar flares. WebWe investigate the occurrence of slipping magnetic reconnection, chromospheric evaporation, and coronal loop dynamics in the 2014 September 10 X-class flare. …

Web2 days ago · While the SXR emission generally lags behind the NUV as expected from the chromospheric evaporation flare models, the Neupert effect is more prevalent in larger, more impulsive flares. Preliminary flaring rate analysis with X-ray and U-band data suggests that previously estimated energy ratios hold for a collection of flares observed over the ...

WebAug 1, 2015 · Chromospheric evaporation was examined in great detail by Fisher et al., who described a distinction between two different regimes, termed explosive and gentle evaporation. In this work, we examine the importance of electron energy and stopping depths on the two regimes and on the atmospheric response. We find that with explosive … WebAug 20, 2009 · CONVERSION FROM EXPLOSIVE TO GENTLE CHROMOSPHERIC EVAPORATION DURING A SOLAR FLARE Full Record Related Research Abstract A GOES M1.5 solar flare was observed in NOAA AR 10652 on 2004 July 27 around 20:00 UT with the Coronal Diagnostic Spectrometer (CDS) aboard the Solar and Heliospheric …
WebThe transition energies between "gentle" and "explosive" evaporation regimes estimated from the observations ( erg cm -2 s -1) and derived from the models ( erg cm -2 s -1) are comparable with each other. The results illustrate relationships among the processes of chromospheric evaporation, the response of the colder layers, and the flare ... 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 ).
