Non-equilibrium ionization by a periodic electron beam II. Synthetic Si IV and O IV transition region spectra
Elena Dzifcakova, Jaroslav Dudik
Transition region (TR) spectra typically show the Si IV 1402.8 A line to be enhanced by a factor of 5 or more compared to the neighboring O IV 1401.2 A, contrary to predictions of…
Expanding and Contracting Coronal Loops as Evidence of Vortex Flows Induced by Solar Eruptions
J. Dudík, F. P. Zuccarello, G. Aulanier +2
Eruptive solar flares were predicted to generate large-scale vortex flows at both sides of the erupting magnetic flux rope. This process is analogous to a well-known hydrodynamic p…
Non-Equilibrium Processes in the Solar Corona, Transition Region, Flares, and Solar Wind \textit{(Invited Review)}
Jaroslav Dudík, Elena Dzifčáková, Nicole Meyer-Vernet +12
We review the presence and signatures of the non-equilibrium processes, both non-Maxwellian distributions and non-equilibrium ionization, in the solar transition region, corona, so…
Non-Maxwellian analysis of the transition-region line profiles observed by the Interface Region Imaging Spectrograph
Jaroslav Dudik, Vanessa Polito, Elena Dzifcakova +2
We investigate the nature of the spectral line profiles for transition region ions observed with the Interface Region Imaging Spectrograph (IRIS). In this context, we have analyzed…
Vortex and sink flows in eruptive flares as a model for coronal implosions
Francesco P. Zuccarello, Guillaume Aulanier, Jaroslav Dudík +3
Eruptive flares are sudden releases of magnetic energy that involve many phenomena, several of which can be explained by the standard 2D flare model and its realizations in three-d…
