The Araucaria Project : the Baade-Wesselink projection factor of pulsating stars

arXiv:1309.4886 · doi:10.1017/S1743921313014233

Abstract

The projection factor used in the Baade-Wesselink methods of determining the distance of Cepheids makes the link between the stellar physics and the cosmological distance scale. A coherent picture of this physical quantity is now provided based on several approaches. We present the lastest news on the expected projection factor for different kinds of pulsating stars in the Hertzsprung-Russell diagram.
