X-ray astronomy primarily involves the study of plasmas with thermal temperatures in the range of 1E6 to 1E8 K. Such plasmas radiate the bulk of their energy in the X-ray regime, from ca. 0.1 to 10 keV. ... Apart from X-ray continuum emission, produced through processes such as e.g. thermal bremsstrahlung, a significant fraction of the total emissivity of hot thermal plasmas can arise from line emission. ... XMM's science objectives are described here in two parts: . General science objectives . ...

... 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). ...
