Fig. 3
Visibility and differential phase variations in the Hα emission line and in the surrounding continuum obtained from our medium spectral-resolution (MR) CHARA/VEGA observations (red). The best-fit kinematic model for this dataset is overplotted in blue. Right bottom panel: Hα intensity profile. Top right panel: elliptical model for the central star 51 Oph and our kinematic model for a purely rotating disk.
