Cepheid distances from infrared long-baseline interferometry III. Calibration of the surface brightness-color relations
The recent VINCI/VLTI observations presented in Paper I have nearly doubled the total number of available angular diameter measurements of Cepheids. Taking advantage of the significantly larger colorExpand

SearchCal: a Virtual Observatory tool for searching calibrators in optical long baseline interferometry. I: The bright object case
In long baseline interferometry, the raw fringe contrast must be calibrated to obtain the true visibility and then those observables that can be interpreted in terms of astrophysical parameters. TheExpand

SearchCal: a Virtual Observatory tool for searching calibrators in optical long-baseline interferometry II. The faint-object case
Context. In long-baseline interferometry, images or astrophysical parameters are obtained from the raw fringe contrast after a careful calibration process. We have already developed the softwareExpand

Direct constraint on the distance of $\gamma^2$ Velorum from AMBER/VLTI observations
In this work, we present the first AMBER observations, of the Wolf-Rayet and O (WR+O) star binary system y² Velorum. The AMBER instrument was used with the telescopes UT2, UT3, and UT4 on baselinesExpand

Darwin--a mission to detect and search for life on extrasolar planets.
The discovery of extrasolar planets is one of the greatest achievements of modern astronomy. The detection of planets that vary widely in mass demonstrates that extrasolar planets of low mass exist.Expand
