The bright blue side of the night sky: Spectroscopic survey of bright and hot (pre-) white dwarfs
Nicole Reindl, Ramazan Islami, Klaus Werner +10
We report on the spectroscopic confirmation of 68 new bright ( mag) and blue (pre-)white dwarfs (WDs). This finding has allowed us to almost double the number of the h…
SHOTGLAS II. MUSE spectroscopy of blue horizontal branch stars in the core of Centauri and NGC 6752
M. Latour, S. Hämmerich, M. Dorsch +5
In this work, we characterize the properties of HB stars in the GCs Cen and NGC 6752. We use dedicated model atmospheres and synthetic spectra grids computed using a hybrid LTE…
The first massive compact companion in a wide orbit around a hot subdwarf star
S. Geier, M. Dorsch, H. Dawson +5
We report the discovery of the first hot subdwarf B (sdB) star with a massive compact companion in a wide () binary system. It was discovered based on an a…
Detailed follow up studies of three ultracompact sdB binaries
Eric Stringer, Thomas Kupfer, Matti Dorsch
We present follow-up studies of three ultracompact hot subdwarf binaries. Using data from the Zwicky Transient Facility, we find orbital periods of 33.6, 37.3, and 36.9 minutes for…
Abundance analysis of a nitrogen-rich extreme-helium hot subdwarf from the SALT survey
L. J. A. Scott., C. S. Jeffery, D. Farren +2
We have performed a detailed spectral analysis of the helium-rich hot subdwarf EC 20187-4939 using data obtained in the SALT survey of helium-rich hot subdwarfs. We have measured i…
