Fig. 11.


Contrast between rigs and gaps versus radial separation. The plain curves are estimated from the theory (Eq. (19)) while the diamond markers are points measured from simulations. The blue, orange, green, and red colours correspond respectively to μeq = 10−4,  10−3.5,  10−3, and 10−2.5. Dotted lines delimit the region above which dust can be concentrated within the rings, assuming H/R = 0.05 (black) and H/R = 0.1 (purple). See Sect. 4.7 for further detail.
