The Expanding Envelope of Supernova 1987A in the Large Magellanic Cloud,project, but also an excellent opportunity to express my thanks to the Bochum Institute Director, Prof. Theodor Schmidt-Kaler, who invested a lot of time and dedication in this programme. In fact this work would have been impossible without his permanent and inspiring support in the background.

Dynamos in Galaxies,ay to explain the observed isotropy of the cosmic radiation. Alfvén, Richtmeyer and Teller (1949), and Fermi (1949) stated that the particles of the cosmic radiation have to be reflected often and this can hardly be explained other than by an interaction with a magnetic field.

Asteroid-Asteroid Interactions - Dynamically Irrelevant?,h the gravitational cross section densities of the terrestrial planets and their influences on the population of planet crossing asteroids indicates that some interactions with the asteroids should lead to observable effects but the involved timescales are difficult to estimate because of the inhomogeneity of the asteroid distribution.

Convection, Spontaneous Discontinuities, and Stellar Winds and X-Ray Emission,e models are the first scientific representation of the static equilibrium of a self-gravitating star. The polytropes are not precise models of a star, but they capture the basic theoretical principles of the balance of thermal pressure against gravity, with a high central temperature declining toward the surface.

First Results from the X-Ray Astronomy Mission ROSAT,educed level of background noise and angular resolution of a few arcseconds up to now. In this respect X-ray astronomy has come close to the performance delivered by ground-based optical telescopes and radio telescopes.
