The years of available space-based photometry have led to the detection the dense oscillation frequency spectra for γ Doradus stars. Theory predicts the presence of non-uniform period spacing series in these frequency spectra, which contain information on the interior stellar structure. We have therefore developed a new method, based on the theoretical expectations and the observational spectroscopic studies, which allows us to detect such spacing patterns. The technique has a high success rate, with detections for ∼60 % of the studied targets, though a notable deficiency is the inability to determine values for the degree l and the azimuthal order m. © Owned by the authors, published by EDP Sciences, 2015.
