Top: one of the best models for a clumpy environment of V854 Cen at two selected wavelengths with 30 clumps. Middle: 2013/2014 combined H (blue) and K (red) band interferometric visibilities obtained with AMBER/VLTI compared with the signal from the polychromatic geometrical modeling. The wavelength label is in μm. Bottom: closure phases. Colors are the same.
