An in-depth study of HD 174966 with CoRoT photometry and HARPS spectroscopy. Large separation as a new observable for \delta Sct stars

An in-depth study of HD 174966 with CoRoT photometry and HARPS spectroscopy. Large separation as a new observable for \delta Sct stars

The aim of this work was to use a multi-approach technique to derive the most accurate values possible of the physical parameters of the \delta Sct star HD174966. In addition, we searched for a periodic pattern in the frequency spectra with the goal of using it to determine the mean …
