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…
NLTE Analysis of the Ultra-short Period White-dwarf Binary RX J0806.3+1527
J. Steiper, K. Reinsch, S. Dreizler
RX J0806.3+1527 is suspected to be a double-degenerate white dwarf binary. We present first results of our NLTE analysis of its optical spectrum. The VLT/FORS1 data show a composit…
Metal Abundances in Hot DA White Dwarfs
S. Schuh, M. A. Barstow, S. Dreizler
We compare measured element abundances in hot DA white dwarfs from UV observations to predictions from our self-consistent non-LTE model atmosphere diffusion calculations.
Discovery of a Long-Period Photometric Variation in the V361 Hya Star HS 0702+6043
S. Schuh, J. Huber, E. M. Green +4
We report the discovery of a long-period g-mode oscillation in the previously known short-period p-mode sdB pulsator HS 0702+6043. This makes this star an extraordinary object, uni…
Iron Abundance in Hydrogen-Rich Central Stars of Planetary Nebulae
A. I. D. Hoffmann, I. Traulsen, T. Rauch +3
We report on an on-going analysis of high-resolution UV spectra of hot hydrogen-rich central stars of planetary nebulae (CSPN), obtained with the Hubble Space Telescope and FUSE. S…
