The near-infrared size-luminosity relations for Herbig Ae/Be disks
We report the results of a sensitive K-band survey of Herbig Ae/Be disk sizes using the 85-m baseline Keck Interferometer. Targets were chosen to span the maximum range of stellar properties to probe the disk size dependence on luminosity and effective ...

Lopsided dust rings in transition disks
Context. Particle trapping in local or global pressure maxima in protoplanetary disks is one of the new paradigms in the theory of the first stages of planet formation. However, finding observational evidence for this effect is not easy.

Organische Trägermaterialien für Ziegler-Natta-Katalysatoren
Ziel dieser Arbeit war die Entwicklung eines auf einem organischen Trägermaterial basierenden Ziegler-Natta-Katalysatorsystems, welches die erforderliche Fragmentierbarkeit in möglichst kleine Fragmente aufweist. Hierfür sah das Konzept dieser Arbeit eine direkte Bildung der aktiven Zentren auf fein dispergierten, Hydroxy-funktionalisierten Polystyrol ...
