The stellar content of the Hamburg/ESO survey. I. Automated selection of DA white dwarfs
N. Christlieb, L. Wisotzki, D. Reimers +3
We describe automatic procedures for the selection of DA white dwarfs in the Hamburg/ESO objective-prism survey (HES). For this purpose, and the selection of other stellar objects…
Cool helium-rich white dwarfs from the Hamburg/ESO Survey
S. Friedrich, D. Koester, N. Christlieb +2
We present an analysis of 40 cool helium-rich white dwarfs found in the Hamburg/ESO survey. They were selected for follow-up spectroscopy because of their U-B colour below -0.18, t…
Abundance analysis of two extremely metal-poor stars from the Hamburg/ESO Survey
E. Depagne, V. Hill, N. Christlieb +1
We report on the first high spectral resolution analysis of extremely metal-poor halo stars from the Hamburg/ESO objective-prism survey (HES). The spectra were obtained with UVES a…
The Hamburg/ESO survey for bright QSOs. III. A large flux-limited sample of QSOs
L. Wisotzki, N. Christlieb, N. Bade +4
We present a new sample of 415 bright QSOs and Seyfert~1 nuclei drawn from the Hamburg/ESO survey (HES). The sample is spectroscopically 99 % complete and well-defined in terms of…
Ongoing Large Surveys for Metal-Poor Stars in the Galactic Halo
Norbert Christlieb, Timothy C. Beers
We report on two major surveys for metal-poor stars in the galactic halo, the HK survey, and the Hamburg/ESO survey, which have been undertaken in order to provide targets for high…
