As an example for an observation of a stellar corona, a simulation of the response of RGS was performed. The input spectrum was a two component Mewe-Kaastra plasma, with solar abundance, and temperatures of 0.35 and 2 keV. ... The following image shows an intensity display of the measured spectrum with dispersion coordinate as measured in the spatial dimension on the RGS Focal Camera (RFC) along the abscissa, and the energy response of the CCDs along the ordinate. ...

... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...
