Spectral analyses of DO white dwarfs and PG1159 stars from the Sloan Digital Sky Survey
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
We present a model atmosphere analysis of ten new DO white dwarfs and five new PG 1159 stars discovered in the Sloan Digital Sky Survey DR1, DR2 and DR3. This is a significant incr…
The Spectral Variability of Pulsating Stars: PG1159-035
T. Stahn, S. Dreizler, K. Werner
With 10m class telescopes as well as with time-tagging detectors on board of HST and FUSE, the analysis of time-resolved spectra for pulsating white dwarfs becomes feasible. We pre…
Spectral Analysis of Super Soft X-ray Sources: V4743 Sagittarii
Thomas Rauch, Marina Orio, R. Gonzales-Riestra +1
Half a year after its outburst, the nova V4743 Sgr evolved into the brightest super-soft X-ray source in the sky with a flux maximum around 30A, exhibiting resonance lines of C V,…
Spectral Analysis of Central Stars of PNe Interacting with the Interstellar Medium
Thomas Rauch, Florian Kerber
Planetary Nebulae (PNe) are the result of heavy mass loss of the asymptotic giant branch (AGB) stars. They are understood in terms of Kwok's (1978) interacting-winds model as the p…
On the Evolutionary Status of Extremely Hot Helium Stars - are O(He) Stars Successors of RCrB Stars?
Thomas Rauch, Elke Reiff, Klaus Werner +3
95% of all stars end their lives as white dwarfs. About 20% of the hot post-AGB stars are hydrogen deficient. Most of these are the result of a late helium-shell flash, but the evo…
AA Dor - An Eclipsing Post Common-Envelope Binary
Thomas Rauch, Klaus Werner
AA Dor (LB 3459) is an eclipsing, close, single-lined, post common-envelope binary (PCEB) consisting of an sdOB primary star and an unseen secondary with an extraordinary small mas…
