  text: We consider the confined Fröhlich polaron and establish an asymptotic series
    for the low-energy eigenvalues in negative powers of the coupling constant. The
    coefficients of the series are derived through a two-fold perturbation approach,
    involving expansions around the electron Pekar minimizer and the excitations of
    the quantum field.
