The KAPPA package is designed for calculations of optically thin spectra for the non-Maxwellian κ -distributions. This paper presents an extension of the database to allow calculations of the spectra for extreme values of κ < 2, which are important

Spectral line intensities observed by the Extreme Ultraviolet Variability Experiment (EVE) on board the Solar Dynamics Observatory (SDO) during 2012 March 9 M6.3 flare were used to diagnose a presence of a non-thermal electron distribution represente

KAPPA is a database and software for the calculation of the optically thin spectra for the non-Maxwellian κ-distributions that were recently diagnosed in the plasma of solar coronal loops, flares, as well as in the transition region. KAPPA is based

We report on observations of flare ribbon kernels during the 2012 August 31 filament eruption. In the 1600\,\AA{} and 304\,\AA{} channels of the Atmospheric Imaging Assembly, flare kernels were observed to move along flare ribbons at velocities $v_\p

Spectroscopic observations made by the Extreme Ultraviolet Variability Experiment (EVE) on board the Solar Dynamics Observatory (SDO) during the 2012 March 7 X5.4-class flare (SOL2012-03-07T00:07) are analyzed for signatures of the non-Maxwellian kap

We analyze the spectra of high temperature \fexxiv~lines observed by \emph{Hinode}/EIS during the impulsive phase of the X8.3--class flare on September 10, 2017. The line profiles are broad, show pronounced wings, and clearly depart from a single Gau

We use the latest available atomic data to calculate the ionisation and recombination rates for the non-Maxwellian $n$ -distributions, which were shown previously to provide a good fit to the enhanced intensities of dielectronic satellite lines durin

Aims. The solar transition region satisfies the conditions for presence of non-Maxwellian electron energy distributions with high-energy tails at energies corresponding to the ionization potentials of many ions emitting in the extreme-ultraviolet and

Emitted spectra reflect the physical conditions in the emitting medium, including the distribution of particle energies. The kappa distributions influence line intensities through the rates of collisional processes involving ionization, recombination
