Gas density distribution at the end of the simulation normalized with respect to the initial distribution around an Earth-mass planet for St = 0.01 in a high-metallicity disk with ε = 0.1. The three different initial disk density profiles with steepness values of p = 0.5,1.0, and 1.5, and the three different accretion efficiencies with values of η = 0,10, and 100%, are shown. The circles represent the planetary Hill sphere. The orbital motion of the planet is indicated.
