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 ( $T_{eff}$ ) and surface gravity (log $g$ ) of a DA white dwarf is by fitting the Hydrogen Lyman and Balm…

Limits on a Gravitational Field Dependence of the Proton--Electron Mass Ratio from H $_{2}$ in White Dwarf Stars

Julija Bagdonaite, Edcel J. Salumbides, Simon P. Preval +4

Spectra of molecular hydrogen (H $_{2}$ ) are employed to search for a possible proton-to-electron mass ratio ( $μ$ ) dependence on gravity. The Lyman transitions of H $_{2}$ , observed with…
