Abstract
We describe some aspects of the energetic radiations of high-energy cosmical plasmas in stellar environments, mainly stellar chromospheres and coronae, and solar and stellar flare-type phenomena. As far as possible we discuss the morphology and physics of these plasmas, and we speculate on their origin. This paper is a review, partly of a historical character, describing particularly some contributions from the Astronomical Institute at Utrecht to this field of astrophysical research.
