Synthetic images at 0.65 μm (polarised intensity) and at 850 μm obtained after radiative transfer calculations, before and after instrument simulations (SPHERE/ZIMPOL and ALMA), using the dust density distributions obtained from model V (Fig. 4, dead zone alone) at different times of evolution. Circles at 20 au (assuming 140 pc distance) is also shown for reference. The star is not suppressed for the scattered optical light images.
