The observation of the strengths and profiles of the hydrogen Balmer absorption series is an established technique for determining the effective temperature and surface gravity of hot H-rich white dwarf stars. In principle, the Lyman series lines should be equally useful but, lying in the far-ultraviolet (FUV), are only accessible from space. Nevertheless, there are situations (for example, where the optical white dwarf spectrum is highly contaminated by the presence of a companion) in which… 
Comparison of the effective temperatures, gravities and helium abundances of DAO white dwarfs from Balmer and Lyman line studies
The use of observations of the hydrogen Balmer absorption series is a well-established method of determining the surface gravity and effective temperature ( T eff ) of white dwarfs. In situations

We present a comparative study of effective temperatures determined from the hydrogen Balmer lines and from the UV energy distribution for 140 DA white dwarfs drawn from the International Ultraviolet
Evidence for an external origin of heavy elements in hot DA white dwarfs
We present a series of systematic abundance measurements for 89 hydrogen atmosphere (DA-type) white dwarfs with temperatures spanning 16 000–77 000 K drawn from the FUSE spectral archive. This is the

We present new measurements of the spatial distribution of cool and hot gas in the local interstellar medium as a result of a search for O VI absorption in the FUV spectra of 100 white dwarfs at
Hubble Space Telescope spectroscopy of the Balmer lines in Sirius B
Sirius B is the nearest and brightest of all white dwarfs, but it is very difficult to observe at visible wavelengths due to the overwhelming scattered light contribution from Sirius A. However, from
A photospheric metal line profile analysis of hot DA white dwarfs with circumstellar material
Some hot DA white dwarfs have circumstellar high ion absorption features in their spectra, in addition to those originating in the photosphere. In many cases, the line profiles of these absorbing
Structure and Evolution of White Dwarfs and their Interaction with the Local Interstellar Medium
The development of far-UV astronomy has been particularly important for the study of hot white dwarf stars. A significant fraction of their emergent flux appears in the far-UV and traces of elements
O VI in the Local Interstellar Medium
TLDR
It appears that there is much less O VI-bearing gas than previously stated within the inner rarefied regions of the local interstellar cavity, and there is no strong evidence to support a spatial correlation between O VI and SXRB emission.
