Interpretation of the near-IR AMBER/VLTI interferometric data using a set of three geometrical models. The best model of the emitting source consists in a primary photospheric disk represented by a uniform disk with a radius of 1.7 mas, a circumstellar environment represented by a Gaussian with FWHM of 4.8 mas, and an unresolved companion represented as a point source located at a projected distance of 1.45 mas from the center of the primary. The relative fluxes are determined for each spectral channel, representing for instance at 2.1 μm 58/30/12% for the primary, circumstellar environment, and secondary, respectively.
