Refining fundamental constants with white dwarfs: machine learning informed constraints on fine-structure constant and proton-to-electron mass ratio

Akhil Uniyal, Surajit Kalita, Yosuke Mizuno +2

We explore the potential variation of two fundamental constants, the fine-structure constant $\hat{I}\pm$ and the proton-to-electron mass ratio $\hat{I}¼$, within the framework of modified gravi…
