Application of state of the art stellar modeling software towards exploring and constraining phenomenological extensions to gravitation

Recently maturing software for stellar modeling and evolution, such as MESA, have been applied to constraining variations of the gravitational constant and exploring such a variation’s ability to account for the Hubble tension between the late- and early- time universe by biasing the local distance ladder.

We will here explore more non-minimal extensions to this phenomenological variation, to see what other behavior that can introduce and whether we can be able to exclude such scenarios by confronting the simulations with telescope data of variable stars.
