Surface brightness-colour relations of Milky Way and Magellanic Clouds classical Cepheids based on Gaia magnitudes
M. C. Bailleul, N. Nardetto, V. Hocdé +12
Aims: We derive SBCRs for classical Cepheids in the Milky Way and in the Magellanic Clouds using the photometric data available in the Gaia database, and we quantify the metallicit…

Surface brightness-colour relations of Cepheids calibrated by optical interferometry
M. C. Bailleul, N. Nardetto, V. Hocdé +12
Surface brightness-colour relations (SBCRs) are widely used to determine the angular diameters of stars. They are in particular used in the Baade-Wesselink (BW) method of distance…
