High-resolution optical spectroscopy of Praesepe white dwarfs
(2009)
We present the results of a high-resolution optical spectroscopic study of nine white dwarf candidate members of Praesepe undertaken with the VLT and Ultraviolet and Visual Echelle Spectrograph. We find, contrary to a ...
A new detailed examination of white dwarfs in NGC 3532 and NGC 2287
(2009)
We present the results of a photometric and spectroscopic study of the white dwarf candidate members of the intermediate age open clusters NGC 3532 and NGC 2287. Of the nine objects investigated, it is determined that six ...
The Origins of the Ultramassive White Dwarf GD50
(Astronomical Society of the Pacific, 2007)
On the basis of astrometric and spectroscopic data we argue that the ultramassive white dwarf GD 50 is associated with the star formation event that created the Pleiades and is potentially a former cluster member. Its ...
FUSE observations of PG1342+444 : new insights into the nature of the hottest DA white dwarfs
(2002)
We present Far Ultraviolet Spectroscopic Explorer (FUSE) observations of the very hot (Teff≈60 000 K) DA white dwarf PG1342+444, describing our data reduction and analysis techniques. The spectrum reveals a number of ...
