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 ...
