Schematic view of the inner 180 au of the HH212 system following our MHD disk-wind modeling. The streamlines rich in SiO are pictured in green, the wider component traced by SO and SO₂ is in black, for launch radii of 0.25, 0.9, 3, 11, and 40 au. The magenta dashed curve shows the boundary of the cavity from Fig. 1. The dusty disk scale height from Lee et al. (2017b) is indicated in blue, the centrifugal barrier in red, and the COMs warm ring in orange (Lee et al. 2017c; Bianchi et al. 2017).
