Multiwavelength Aspects of Stellar Coronae
Manuel Guedel
Abstract
Coronae express different facets of their energy release processes in different wavelength regions. While soft X-ray and EUV emission dominates the radiative losses of the thermal plasma, hard X-ray emission (>10 keV) can be produced from non-thermal high-energy particles accelerated as a consequence of flare processes, and radio emission is often emitted from mildly relativistic electrons trapped in magnetic fields. Combined measurements of all emissions are important to understand the ultimate mechanisms responsible for coronal energy release and heating. This presentation will summarize a number of aspects for which multi-wavelength studies are important, both for quiescent and flare emission.
