Fig. 4From: Planetesimal formation by an axisymmetric radial bump of the column density of the gas in a protoplanetary diskDust density distribution around \(x_+\). The dust density is normalized by \(\rho _{g0}\) (the dust density shown in the inlet is normalized by \(\rho _{\rm Roche}=3.8 \times 10^2 \rho _{g0}\))Back to article page
