Far-ultraviolet spectroscopy of the hot DA white dwarf WD 2218 706 (DeHt5) with STIS
Barstow, M.A.; Bannister, N.P.; Holberg, J.B.; Hubeny, I.; Bruhweiler, F.C.; Napiwotzki, R. (2001)We report a study of the photospheric composition of the hot DA white dwarf WD 2218+706, which is also the central star of the old planetary nebula DeHt5. Helium is detected in the far-UV spectrum. In addition, the star ... -
FUSE observations of PG1342+444 : new insights into the nature of the hottest DA white dwarfs
Barstow, M.A.; Good, S.A.; Holberg, J.B.; Burleigh, M.R.; Bannister, N.P.; Hubeny, I.; Napiwotzki, R. (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 ... -

Heavy Elements in DA White Dwarfs
Barstow, M.A.; Burleigh, M.R.; Bannister, N.P.; Holberg, J.B.; Hubeny, I.; Bruhweiler, F.C.; Napiwotzki, R. (Astronomical Society of the Pacific, 2001) -
Heavy-element abundance patterns in hot DA white dwarfs
Barstow, M.A.; Good, S.A.; Holberg, J.B.; Hubeny, I.; Bannister, N.P.; Bruhweiler, F.C.; Burleigh, M.R.; Napiwotzki, R. (2003-05) -
A near-infrared spectroscopic search for very-low-mass cool companions to notable DA white dwarfs
Dobbie, P.D.; Burleigh, M.R.; Levan, A.; Barstow, M.A.; Napiwotzki, R.; Holberg, J.B.; Hubeny, I.; Howell, S.B. (2005) -
A near-IR spectrum of the DO white dwarf RE J0503-285
Dobbie, P.D.; Burleigh, M.R.; Levan, A.; Barstow, M.A.; Napiwotzki, R.; Hubeny, I. (2005) -
A new detailed examination of white dwarfs in NGC 3532 and NGC 2287
Dobbie, P.D.; Napiwotzki, R.; Burleigh, M.R.; Williams, K.A.; Sharp, R.G.; Barstow, M.A.; Casewell, S.L.; Hubeny, I. (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 ... -
New Praesepe white dwarfs and the initial mass final mass relation
Dobbie, P.D.; Napiwotzki, R.; Burleigh, M.R.; Barstow, M.A.; Boyce, D.D.; Casewell, S.L.; Jameson, R.F.; Hubeny, I.; Fontaine, G. (2006) -
