H 1504+65 is an extremely hot hydrogen-deficient white dwarf with an effective temperature close to 200 000 K. We present new FUV and soft X-ray spectra obtained with FUSE and Chandra, which confirm that H 1504+65 has an atmosphere primarily composed of carbon and oxygen. The Chandra LETG spectrum (60 - 160A) shows a wealth of photospheric absorp- tion lines from highly ionized oxygen, neon, and - for the firs t time identified in this star - magnesium and suggests relati vely high Ne and Mg… Expand
UV spectroscopy of the hot bare stellar core H1504+65 with the HST Cosmic Origins Spectrograph
We present new ultraviolet spectra of the hottest known, peculiar white dwarf H1504+65, obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope. H1504+65 is the hottest knownExpand
Line identification in soft X-ray spectra of stellar coronae by comparison with the hottest white dwarf's photosphere: Procyon, α Cen A+B, and H 1504+65
H 1504+65 is a young white dwarf with an effective temperature of 200 000 K and is the hottest post-AGB star ever analysed with detailed model atmospheres. Chandra LETG+HRC-S spectra have revealedExpand
Analysis of HST/COS spectra of the bare C-O stellar core H1504+65 and a high-velocity twin in the Galactic halo
H1504+65 is an extremely hot white dwarf (effective temperature Teff = 200,000 K) with a carbon-oxygen dominated atmosphere devoid of hydrogen and helium. This atmospheric composition was hithertoExpand
DEPOSING THE COOL CORONA OF KPD 0005+5106
The ROSAT PSPC pulse-height spectrum of the peculiar He-rich hot white dwarf KPD 0005+5106 provided a great surprise when first analyzed by Fleming, Werner, & Barstow. It defied the best non-LTEExpand
Identification of neon in FUSE and VLT spectra of extremely hot hydrogen-deficient (pre-) white dwarfs ,
One of the strongest absorption lines observed in far-ultraviolet FUSE spectra of many PG 1159 stars remained unidentified up to now. We show that this line, located at 973.3 A, stems from Ne . WeExpand
Discovery of photospheric Ca X emission lines in the far-UV spectrum of the hottest known white dwarf (KPD 0005+5106)
For the first time, we have identified photospheric emission lines in the far-UV spectrum of a white dwarf. They were discovered in the Far Ultraviolet Spectroscopic Explorer spectrum of the hotExpand
Chandra grating spectroscopy of three hot white dwarfs
Context. High-resolution soft X-ray spectroscopic observations of single hot white dwarfs are scarce. With the Chandra Low-Energy Transmission Grating, we have observed two white dwarfs, one is ofExpand
Identification of a DO white dwarf and a PG 1159 star in the ESO SN Ia progenitor survey (SPY)
TLDR
High-resolution VLT spectra are presented of a new helium-rich DO white dwarf (HE1314+0018) and a new PG 1159 star (HE1429−1209), which were identified in the ESO SPY survey. Expand
The Elemental Abundances in Bare Planetary Nebula Central Stars and the Shell Burning in AGB Stars
We review the observed properties of extremely hot, hydrogen-deficient post-asymptotic giant branch (AGB) stars of spectral type (WC) and PG1159. Their H deficiency is probably caused by a (very)Expand
Two SMC Symbiotic Stars Undergoing Steady Hydrogen Burning
Two symbiotic stars in the Small Magellanic Cloud (SMC), Lin 358 and SMC 3, have been supersoft X-ray sources (SSSs) for more than 10 years. We fit atmospheric and nebular models to their X-ray,Expand
