Abstract:
Recent imaging observations of transitional discs have revealed that in some targets, the gap measured using sub-mm “disappears” when observed using near-infrared polarimetry, suggesting that the “empty” region is actually filled with small particles of dust. Assuming the gapped structure observed in transitional discs is caused by the presence of a planet, we try to explain such discrepancies simulating observations of physical models of disc-planet systems with SPHERE-ZIMPOL, HiCIAO, VISIR and ALMA.
