The EUV Spectrum of the Sun: Quiet- and Active-Sun Irradiances and Chemical Composition [PDF]
Astronomy and Astrophysics, 2019 We benchmark new atomic data against a selection of irradiances obtained from medium-resolution quiet-Sun spectra in the extreme ultraviolet (EUV), from 60 to 1040 Å. We used as a baseline the irradiances measured during solar minimum on 2008 April 14 by the prototype (PEVE) of the Solar Dynamics Observatory Extreme ultraviolet Variability Experiment ...

The title of this chapter presupposes that there exists a Sun that is Non-active or Quiet. Modern research, however, is discovering more and more that there is no such thing as a perfectly placid Sun. Activity occurs on all scales at all times in the solar atmosphere.

The Sun is the star closest to us and the only star where details can be directly observed. By comparison of the parameters describing the Sun with other stars, we understand the physics of stars in more detail and by comparing e.g. our present Sun with stars that are younger or older than the Sun, we can learn about the evolution of the Sun, its ...
