Asteroseismology: Looking for Axions in the Red Supergiant Star Alpha Ori
In this work, for the first time, we use seismic data as well as surface abundances to model the supergiant α -Ori, with the goal of setting an upper bound on the axion–photon coupling constant g _a _γ . We find that, in general, stellar models with g _a _γ ∈ [0.002; 2.0] × 10 ^−10 GeV ^−1 agree wit...
