The lack of close binaries among hot horizontal branch stars in NGC6752
C. Moni Bidin, S. Moehler, G. Piotto +3
We present the results of a spectroscopic search for close binaries among horizontal branch (HB) stars in NGC6752. We used the ESO VLT-FORS2 instrument to obtain medium resolution…
Do weak magnetic fields prevent hydrogen from accreting onto metal-line white dwarf stars?
Susanne Friedrich, Stefan Jordan, Detlev Koester
The widely accepted assumption is that metals detected in the spectra of a few cool helium-rich white dwarfs cannot be of primordial origin and therefore must be accreted from the…
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…
On the evolution of shape in N-body simulations
Ch. Theis, R. Spurzem
A database on shape evolution of direct N-body models formed out of cold, dissipationless collapse is generated using GRAPE and HARP special purpose computers. Such models are impo…
