Limits on a Gravitational Field Dependence of the Proton{Electron Mass Ratio from H2 in White Dwarf Stars

Bagdonaite, J; Salumbides, EJ; Preval, SP; Barstow, MA; Barrow, John David; Murphy, MT; Ubachs, W (American Physical SocietyPhysical Review Letters, 2014-09-18)

Spectra of molecular hydrogen (H2) are employed to search for a possible proton-to-electron mass ratio (μ) dependence on gravity. The Lyman transitions of H2, observed with the Hubble Space Telescope towards white dwarf ...
