Échelle diagram of the power spectrum of HD 49385 derived from 137 days of CoRoT data, folded with a mean large separation Δν = 56.3   μHz. The frequencies of a MS model and a PoMS model are overplotted in blue and red, respectively. The models have been computed to reproduce the observed ℓ = 0 large separation as well as the position of the star in the HR diagram and the PoMS has an ℓ = 1 avoided crossing at low frequency. Squares represent ℓ = 0 modes, triangles ℓ = 1 modes and diamonds ℓ = 2 modes.
