Supernova Cosmology and the Fine Structure Constant
arXiv:astro-ph/0306486 · doi:10.1143/PTP.110.195
Abstract
We study the dependence of the peak luminosity of Type Ia supernovae on the fine structure constant $α$. We find that decreasing (increasing) $α$ enhances (reduces) the luminosity. Future experiments like SNAP could determine the variation of $α$ to a precision of $10^{-2}$.
