This volume contains a comprehensive treatment of X-ray spectroscopy, as applied in astrophysics. It is presented in the form of extensive notes of lectures given by seven distinguished scientists at the Tenth Summer School of the European Astrophysics Doctoral Network. The subjects covered are: basic line & continuum radiation processes in X-ray & gamma-ray astronomy; atomic physics of collision- & radiation-dominated plasmas; X-ray spectroscopic observations with ASCA & BeppoSAX; future X-ray spectroscopy missions; X-ray optics, & X-ray spectroscopy instrumentation. The book, which will appeal to both researchers & graduate students, is timely in view of the scheduled launches of the big X-ray observatories AXAF & XMM in 1999.
