Cepheid distances from infrared long-baseline interferometry

Abstract

We report the angular diameter measurements of seven classical Cepheids, X Sgr, Aql, W Sgr, Gem, Dor, Y Oph and Car that we have obtained with the VINCI instrument, installed at ESO's VLT Interferometer (VLTI). We also present reprocessed archive data obtained with the FLUOR/IOTA instrument on Gem, in order to improve the phase coverage of our observations. We obtain average limb darkened angular diameter values of
