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…
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…
NLTE spectral analysis of GW Vir pulsators
E. Reiff, D. Jahn, T. Rauch +3
GW Vir variables are the pulsating members in the spectroscopic class of PG 1159 stars. In order to understand the characteristic differences between pulsating and non-pulsating PG…
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…
