Ovi Column Density Distribution in the Local Bubble - Results from 3D Adaptive Mesh Refinement Simulations
Miguel A. de Avillez, Dieter Breitschwerdt
The Local Bubble (LB) is an X-ray emitting region extending 100 pc in radius in the Galactic plane and 300 pc perpendicular to it, and it is embedded in a somewhat larger H{\sc i}…
Keynote Lecture: Galactic and Extragalactic Bubbles
D. Breitschwerdt, M. A. de Avillez, M. J. Freyberg
The observational and theoretical state of Galactic and extragalactic bubbles are reviewed. Observations of superbubbles are discussed, with some emphasis on nearby bubbles such as…
Metal Enrichment and Energetics of Galactic Winds in Galaxy Clusters
W. Kapferer, D. Breitschwerdt, W. Domainko +4
We investigate efficiency and time dependence of metal enrichment processes in the Intra-Cluster Medium (ICM). In this presentation we concentrate on the effects of galactic winds.…
On application of multi-colour photometry of Scuti stars
J. Daszy{ń}ska-Daszkiewicz, W. A. Dziembowski, A. A. Pamyatnykh
In Scuti star models, the photometric amplitudes and phases exhibit a strong dependence on convection, which enters through the complex parameter, , which describes the bolo…
Survey of Large Planetary Nebulae in Decay
Thomas Rauch, Elise Furlan, Florian Kerber +1
The Planetary Nebulae (PNe) return nuclear processed stellar material back to the interstellar medium (ISM) and thus have an important influence on the chemical evolution of our Ga…
Optical properties of carbon grains: Influence on dynamical models of AGB stars
Anja C. Andersen, Rita Loidl, Susanne Hofner
For amorphous carbon several laboratory extinction data are available, which show quite a wide range of differences due to the structural complexity of this material. We have calcu…
