Results of DTPS with ρ _m = 10⁻³ g cm⁻³ and T ₁ = 100 K. Left: (a) solid surface density, ﹩{\rm{\Delta }}{{\rm{\Sigma }}}_{{\rm{s}}}/{\rm{\Delta }}\mathrm{ln}m﹩ at t = 2.3 × 10⁵ yr, as a function of the mass of bodies and the distance from the host star. The values of the solid surface density are shown in the color bar. Right: protoplanet mass (b) and total solid surface density (c), as a function of the distance from the host star.
