Current and future white dwarf mass-radius constraints on varying fundamental couplings and unification scenarios
@article{Magano2017CurrentAF, title={Current and future white dwarf mass-radius constraints on varying fundamental couplings and unification scenarios}, author={D. Magano and Jo{\~a}o Vilas Boas and Carlos J. A. P. Martins}, journal={Physical Review D}, year={2017}, volume={96}, pages={083012} }
We discuss the feasibility of using astrophysical observations of white dwarfs as probes of fundamental physics. We quantify the effects of varying fundamental couplings on the white dwarf mass-radius relation in a broad class of unification scenarios, both for the simple case of a polytropic stellar structure model and for more general models. Independent measurements of the mass and radius, together with direct spectroscopic measurements of the fine-structure constant in white dwarf…
