Measuring the fine structure constant on a white dwarf surface; a detailed analysis of Fe V absorption in G191-B2B
J. Hu, J. K. Webb, T. R. Ayres +12
The gravitational potential phi = GM/Rc^2 at the surface of the white dwarf G191-B2B is 10,000 times stronger than that at the Earth's surface. Numerous photospheric absorption fea…

Quantum mechanics at high redshift -- Modelling Damped Lyman- absorption systems
C. C. Lee, J. K. Webb, R. F. Carswell
For around 100 years, hydrogen spectral modelling has been based on Voigt profile fitting. The semi-classical Voigt profile is based on a 2-level atom approximation. Whilst the Voi…

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…
