After showing that the anelastic approximation is better than the subseismic\none to filter out acoustic waves when studying low-frequency stellar\noscillations, we compute gravito-inertial modes of a typical Gamma-Doradus star\nusing this approximation. We show that eigenmodes can be regular or singular,\naccording to the possible focusing towards attractors of the underlying\ncharacteristics. Consequences on the oscillations spectrum are then discussed.\n
