GD358: three decades of observations for the in-depth asteroseismology of a DBV star
Agnes Bischoff-Kim, J. L. Provencal, P. A. Bradley +38
We report on the analysis of 34 years of photometric observations of the pulsating helium atmosphere white dwarf GD358. The complete data set includes archival data from 1982-2006,…
Search for trans-iron elements in hot, helium-rich white dwarfs with the HST Cosmic Origins Spectrograph
D. Hoyer, T. Rauch., K. Werner +1
The metal abundances in the atmospheres of hot white dwarfs (WDs) entering the cooling sequence are determined by the preceding Asymptotic Giant Branch (AGB) evolutionary phase and…
Stellar parameters for the central star of the planetary nebula PRTM 1 using the German Astrophysical Virtual Observatory service TheoSSA
T. Rauch, M. Demleitner, D. Hoyer +1
The German Astrophysical Virtual Observatory (GAVO) developed the registered service TheoSSA (theoretical stellar spectra access) and the supporting registered VO tool TMAW (Tuebin…
Stellar laboratories. IX. New Se V, Sr IV - VII, Te VI, and I VI oscillator strengths and the Se, Sr, Te, and I abundances in the hot white dwarfs G191-B2B and RE 0503-289
T. Rauch, P. Quinet, M. Knoerzer +4
To analyze spectra of hot stars, advanced non-local thermodynamic equilibrium (NLTE) model-atmosphere techniques are mandatory. Reliable atomic data is for the calculation of such…
Complete spectral energy distribution of the hot, helium-rich white dwarf RX J0503.9-2854
D. Hoyer, T. Rauch, K. Werner +2
In the line-of-sight toward the DO-type white dwarf RX J0503.9-2854, the density of the interstellar medium (ISM) is very low, and thus the contamination of the stellar spectrum al…
Stellar laboratories. VII. New Kr IV - VII oscillator strengths and an improved spectral analysis of the hot, hydrogen-deficient DO-type white dwarf RE0503-289
T. Rauch, P. Quinet, D. Hoyer +4
For the spectral analysis of high-resolution and high-signal-to-noise (S/N) spectra of hot stars, state-of-the-art non-local thermodynamic equilibrium (NLTE) model atmospheres are…
