The Araucaria Project: the Baade-Wesselink projection factor of pulsating stars and interferometric contribution to the eclipsing binaries technique of distance determination

The international Araucaria Project aims to provide an improved local calibration of the extragalactic distance scale out to distances of a few Megaparsecs. We present a brief, up-to-date review of different results and ongoing projects to (i) better understand the Baade-Wesselink projection factor used in distance determinations based on Cepheids, and (ii) improve the eclipsing-binary technique of distance determination using CHARA/VEGA interferometric observations.
