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…
