Metal Enrichment of the Intra-Cluster Medium: Ram-Pressure Stripping of Cluster Galaxies
W. Domainko, W. Kapferer, S. Schindler +4
We present numerical simulations of the dynamical and chemical evolution of galaxy clusters. X-ray spectra show that the intra-cluster medium contains a significant amount of metal…
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.…
Symbiotic Miras vs. Planetary Nebulae in the Near Infrared
S. Schmeja, S. Kimeswenger
While symbiotic Miras and planetary nebulae are hard to distinguish by optical spectroscopy, their near infrared colors differ. We propose the near infrared two-color diagram to be…
DENIS Survey Data Probing Different Types of PNe
S. Schmeja, S. Kimeswenger
We present near-infrared photometry of a large sample of planetary nebulae (PNe) and show that the IJK colours are a good tool to distinguish different classes of PNe, like nebulae…
Effects of CSPN Models on PNe Shell Modeling
B. Armsdorfer, S. Kimeswenger, T. Rauch
Modeling planetary nebulae (PNe) shells using different ionizing spectra for a hot central star (CSPN) of evolved PNe, we found that especially a blackbody model leads to wrong neb…
A catalogue of IJK photometry of Planetary Nebulae with DENIS
S. Schmeja, S. Kimeswenger
Near-infrared photometry of planetary nebulae (PNe) allows the classification of those objects. We present the largest homogeneous sample so far, obtained with the Deep Near Infrar…
