Comparison of gas density distributions in NBR and BR models for St = 0.01, 0.1, 1, and 2, with three different accretion efficiencies (η = 0, 0.1, and 1), in the vicinity of 1 M_⊕ planet. The axes are shown in code units. Colors ranging from blue to red represent increasing gas densities in the BR models. Regions where the two models agree are show in white. The black circle indicates the planetary Hill sphere. Note that the density ratios are multiplied by 1000 for clarity.
