Measuring chemical evolution and gravitational dependence of αusing ultraviolet Fe V and Ni V transitions in white-dwarf spectra
A. Ong, J. C. Berengut, V. V. Flambaum
In this paper, we present the details of the ab initio high-precision configuration interaction and many-body perturbation theory calculations that were used in a previous work to…

Limits on the dependence of the fine-structure constant on gravitational potential from white-dwarf spectra
J. C. Berengut, V. V. Flambaum, A. Ong +5
We propose a new probe of the dependence of the fine structure constant, alpha, on a strong gravitational field using metal lines in the spectra of white dwarf stars. Comparison of…
