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…
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…
Shock-reflected electrons and X-ray line spectra
Elena Dzifcakova, Marek Vandas, Marian Karlicky
The aim of this paper is to try to explain the physical origin of the non-thermal electron distribution that is able to form the enhanced intensities of satellite lines in the X-ra…
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…
