Outcome of three simulations with ﹩r=100﹩ m and ﹩\alpha =3\times 10^{-5}﹩. The value of ﹩\Sigma _{\mathrm{solid}\,}﹩ at 5 AU in each case is indicated. Surviving planets are represented by circles with radius ∝M^1/3. The black and gray segments of each circle give the solid and gas mass fractions, respectively. The last row of circles marked "Sol Sys" shows the giant planets of the solar system.
