Chromospheric evaporation
WebMar 19, 2016 · We investigate the occurrence of slipping magnetic reconnection, chromospheric evaporation, and coronal loop dynamics in the 2014 September 10 X-class flare. The slipping reconnection is found to be present throughout the flare from its early phase. Flare loops are seen to slip in opposite directions towards both ends of the … WebWith observations of the Interface Region Imaging Spectrograph (IRIS), we study chromospheric heating and evaporation during an M1.6 flare SOL2015-03-12T11:50. …

WebThese observations suggest that magnetic reconnection can not only form the magnetic field structure of the filament but also heat the chromospheric footpoints during their formation and drive chromospheric evaporation. 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 …
WebNov 29, 2011 · We find clear evidence for typical chromospheric evaporation associated with small transient brightenings, using the data from the X-ray Telescope (XRT) onboard Hinode. We found 13 events, each having a pair of evaporation upflows arising almost symmetrically from both foot points of a magnetic loop. These facts strongly support the … WebChromospheric evaporation is considered to be the main mechanism for transporting the hot SXR-emitting flare plasma to coronal levels (Antonucci et al. 1984). Reviews on this subject can be found in Doschek et al. (1986), Antonucci (1989), Doschek (1990), and Antonucci et al. (1994). The chromospheric evaporation process has thus far been
WebHudson and Ohki (1972) pointed out that the increase of the soft X-ray emission measure during flares might be accounted for in two different ways, either by … WebJul 13, 2024 · Here and below, the p-rocesses that result in heating dense (usually chromospheric) plasmas, which then fill coronal loops (that is the “chromospheric evaporation”), are called chr-omospheric effects (an increase in ЕМ, where ЕМ = n 2 V).
WebThe third stage of chromospheric evaporation has been extensively explored with hydrodynamic simulations, in particular to explain the observed Doppler shifts in soft X-ray lines, while application of spatial models to imaging data is quite sparse.
