Baade-Wesselink Radii of Long Period Cepheids New Observational Results
Published online by Cambridge University Press: 12 April 2016
Abstract
The radii of Galactic Cepheids as determined from a version of the Baade-Wesselink technique are shown to depend upon the colour index used to define the temperature scale. The (V-l) radii are systematically larger than the commonly used (B-V) radii and are probably better estimators of the true radii. There still remains a problem, however, in reconciling the period-radius relation with the period-luminosity-colour relation.
