TL;DR: A review of studies of elemental abundances and emission measures in quiescent solar active region cores is presented in this paper, using upto-date atomic data, older X-ray observations obtained by a sounding rocket and by the Solar Maximum Mission (SMM) Flat Crystal Spectrometer (FCS).

TL;DR: In this paper, the formation of the transition region O IV and Si IV lines observable by the Interface Region Imaging Spectrograph (IRIS) is investigated for both Maxwellian and non-Maxwellian conditions characterized by a κ-distribution exhibiting a high-energy tail.

TL;DR: In this article, the presence and signatures of non-equilibrium processes, both non-Maxwellian distributions and nonequilibrium ionization, in the solar transition region, corona, solar wind, and flares are reviewed.

TL;DR: In this article, a multi-wavelength analysis of 20 EUV jets which occurred at the periphery of active regions close to sunspots is presented, where the authors discuss the physical parameters of the jets and their relation with other phenomena such as Hα surges, nonthermal type-III radio bursts and hard X-ray (HXR) emission.

TL;DR: In this article, the formation of the transition region O IV and Si IV lines observable by the Interface Region Imaging Spectrograph (IRIS) is investigated for both Maxwellian and non-Maxellian conditions characterized by a kappa-distribution exhibiting a high-energy tail.
