UV and FUV spectroscopy of the hybrid PG 1159-type central star NGC 7094
M. Ziegler, T. Rauch, E. Reiff +3
Previous studies aiming at the iron-abundance determination in three PG 1159 stars (K 1-16, PG 1159-035, NGC 7094) and a [WC]-PG 1159 transition star (Abell 78) have revealed that…
O(He) Stars
T. Rauch, E. Reiff, K. Werner +1
Spectral analyses of H-deficient post-AGB stars have shown that a small group of four extremely hot objects exists which have almost pure He absorption-line spectra in the optical.…
Hyperflares of SGRs as an engine for millisecond extragalactic radio bursts
S. B. Popov, K. A. Postnov
We propose that the strong millisecond extragalactic radio burst (mERB) discovered by Lorimer et al. (2007) may be related to a hyperflare from an extragalactic soft gamma-ray repe…
FUV Spectroscopy of the sdOB Primary of the Eclipsing Binary System AA Dor
Johannes Fleig, Thomas Rauch, Klaus Werner +1
AA Dor is an eclipsing, close, post common-envelope binary (PCEB). We present a detailed spectral analysis of its sdOB primary star based on observations obtained with the Far Ultr…
Spectral Analysis of Central Stars of Planetary Nebulae
Thomas Rauch, Klaus Werner, Marc Ziegler +2
Spectral analysis by means of NLTE model atmospheres has presently arrived at a high level of sophistication. High-resolution spectra of central stars of planetary nebulae can be r…
