Studying hot evolved stars with ultraviolet spectroscopy
Stephan Geier, Nicole Reindl, Matti Dorsch +7
Hot evolved stars are key objects to reconstruct the various evolutionary pathways of Sun-like stars, to probe binary interactions and the physics of supernovae. They serve as powe…
Spectral evolution of hot hybrid white dwarfs: II. Photometry
Semih Filiz, Nicole Reindl, David Jones +4
We present a photometric analysis of 19 DA and 13 DAO white dwarfs (WDs) with effective temperatures exceeding 60 kK, building on the spectral analysis reported in the first paper…
Spectral evolution of hot hybrid white dwarfs I. Spectral analysis
Semih Filiz, Klaus Werner, Thomas Rauch +1
Hydrogen-rich white dwarfs (WDs) comprise the majority of the WD population, but are only rarely found at the very hot end of the WD cooling sequence. A small subgroup that exhibit…
Mysterious, Variable, and Extremely Hot: White Dwarfs Showing Ultra-High Excitation Lines I. Photometric Variability
Nicole Reindl, Veronika Schaffenroth, Semih Filiz +3
About 10% of all stars exhibit absorption lines of ultra-high excited (UHE) metals (e.g. OVIII) in their optical spectra when entering the white dwarf cooling sequence. The recent…
