A far-UV survey of three hot, metal-polluted white dwarf stars: WD0455-282, WD0621-376, and WD2211-495
S. P. Preval, M. A. Barstow, M. Bainbridge +7
Using newly obtained high-resolution data () from the \textit{Hubble Space Telescope}, and archival UV data from the \textit{Far Ultraviolet Spectroscopic E…
Constraining the magnetic field on white dwarf surfaces; Zeeman effects and fine structure constant variation
J. Hu, J. K. Webb, T. R. Ayres +12
White dwarf atmospheres are subjected to gravitational potentials around times larger than occur on Earth. They provide a unique environment in which to search for any possi…
Hot DA white dwarf model atmosphere calculations: Including improved Ni PI cross sections
S. P. Preval, M. A. Barstow, N. R. Badnell +2
To calculate realistic models of objects with Ni in their atmospheres, accurate atomic data for the relevant ionization stages needs to be included in model atmosphere calculations…
Understanding the spectrum of the very hot DA white dwarf PG0948+534
S. P. Preval, M. A. Barstow
PG0948+534 is currently one of the hottest DA white dwarf stars, and is also one of the most mysterious. Attempts to model the sharp, deep absorption features of this star have bee…
Do the constants of nature couple to strong gravitational fields?
S. P. Preval, M. A. Barstow, J. B. Holberg +5
Recently, white dwarf stars have found a new use in the fundamental physics community. Many prospective theories of the fundamental interactions of Nature allow traditional constan…
A possible solution to the Lyman/Balmer line problem in hot DA white dwarfs
S. P. Preval, M. A. Barstow, N. R. Badnell +2
Arguably, the best method for determining the effective temperature () and surface gravity (log ) of a DA white dwarf is by fitting the Hydrogen Lyman and Balm…
