Predicted large separation as a function of the mean density of the star, normalized to their solar values, Δν_⊙ = 134.8  μHz (Kjeldsen et al. 2008) and (Haynes et al. 2012), respectively. Contours in grey scale indicate the predicted frequency of the fundamental radial mode. Filled dots, empty dots, and star symbols represent mean densities found in this work, in the literature, and using Tingley’s calibration, respectively. Stars are labeled as in Table 2. For the sake of clarity, the error bars in star symbol estimates are omitted, since they are larger than the abscissa range. Colors are only available in the online version of the paper.
