Cepheid distances from the SpectroPhoto-Interferometry of Pulsating Stars (SPIPS) Application to the prototypes delta Cephei and eta Aquilae

摘要

Context. The parallax of pulsation, and its implementations such as the Baade-Wesselink method and the infrared surface brightness technique, is an elegant method to determine distances of pulsating stars in a quasi-geometrical way. However, these classical implementations in general only use a subset of the available observational data.
