dc.description.abstract | Probing the dynamical structure of Cepheid atmospheres is of primary importance in order to better constrain the cosmic distance ladder. It is indeed now well-known that the projection factor (or p-factor), that is used in the Baade-Wesselink method of distance determination of Cepheids, is sensitive to the atmospheric velocity gradient and other subtle dynamical effects. Relying on HARPS-N high resolution spectroscopic observations, we have measured the atmospheric velocity gradient of δ Cep for the first time, and we found an agreement with the hydrodynamical model of the star. Besides, the mysterious k-term, a residual γ-velocity of the order of 1-2 km s^{-1}, seen in HARPS-N data of δ Cep, is now physically understood thanks to recently published predicted spectroscopic properties of two-dimensional time-dependent Cepheid models. | en_US |
