Radiation and Structure of the Solar Atmosphere,There has been increasing evidence that solar activity, which is basically of magnetic origin, occurs on a great variety of scales and thus immediately touches upon the structure of the solar atmosphere as well as the structure and dynamics of the convection zone. As a consequence progress in the fi

Physical Study of Planets and Satellites,space exploration by spacecraft, but also to the use of modern detectors, of large ground-based telescopes, and of powerful computers by active researchers. Planetary research (or planetology) is a pluridisciplinary domain, which requires not only the competence of astronomers, but also of geophysic
