Abstract
It is well known that alternative theories to the Standard Model allow fundamental constants, such as the fine structure constant, to vary. One way to investigate these variations is to utilize the mass-radius relation of compact objects, which is inherently affected by alpha variations. As such, we initially construct the model of a polytropic white dwarf, which we perturb by adding the alpha variations for various GUT models. We continue our analysis with neutron stars, investigating both polytropic and more realistic equations of state. We outline how future observations might distinguish between extensions of the Standard Model.
