Description
It is well known that alternative theories to the Standard Model allow
fundamental constants, such as the fine structure constant, to vary in
spacetime. One way to investigate these variations is to utilize the Mass-
Radius relation of compact objects, which is inherently affected by α
variations. As such, we initially construct the model of a polytropic
white dwarf, which we perturb by adding the α 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.
