Publisher's Synopsis
A comprehensive overview of current astrophysical research in the wavelength band 100-1200 A is presented in the form of 28 papers, including both theoretical and instrumental aspects. The astronomical objects covered range from stars and stellar systems, the diffuse interstellar medium to external galaxies and distant active galactic nuclei. A key role in this wavelength region is played by spectroscopy, because of the richness of this wavelength band in spectral lines, the diagnostic potential of which is addressed in detail in a number of papers.
