Light and heavy metal abundances in hot central stars of planetary nebulae
K. Werner, A. I. D. Hoffmann, D. Jahn +5
We present new results from our spectral analyses of very hot central stars achieved since the last IAU Symposium on planetary nebulae held in Canberra 2001. The analyses are mainl…
High-resolution ultraviolet spectroscopy of PG1159-035 with HST and FUSE
D. Jahn, T. Rauch, E. Reiff +3
PG1159-035 is the prototype of the PG1159 spectral class which consists of extremely hot hydrogen-deficient (pre-) white dwarfs. It is also the prototype of the GW Vir variables, w…
First application studies at the laser-driven LIGHT beamline: Improving proton beam homogeneity and imaging of a solid target
D. Jahn, D. Schumacher, C. Brabetz +7
In the last two decades, the generation of intense ion beams based on laser-driven sources has become an extensively investigated field. The LIGHT collaboration combines a laserdri…
Simulation Studies on Generation, Handling and Transport of laser-accelerated Carbon Ions
J. Ding, D. Schumacher, D. Jahn +2
To this day the interaction of high-intensity lasers with matter is considered to be a possible candidate for next generation particle accelerators. Within the LIGHT collaboration…
On the Influence of Delay Line Uncertainty in THz Time-Domain Spectroscopy
D. Jahn, S. Lippert, M. Bisi +3
Terahertz time-domain spectroscopy (THz TDS) is a well-known tool for material analysis in the terahertz frequency band. One crucial system component in every time-domain spectrome…
AGB star intershell abundances inferred from analyses of extremely hot H-deficient post-AGB stars
K. Werner, D. Jahn, T. Rauch +3
The hydrogen-deficiency in extremely hot post-AGB stars of spectral class PG1159 is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse that consumes t…
