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…

Discovery of ionized circumstellar gas emission around the long-period Cepheid Carinae with ALMA
V. Hocdé, T. Kamiński, M. Lewis +3
Cepheid circumstellar emissions have previously been detected via both infrared excess and infrared interferometric observations at a few stellar radii. Those studies have shown th…
