Notes. Columns 2, 3, and 4 show the initial disc mass, the disc diffusion timescale, and the corresponding viscosity αacc, respectively.The last column is the total pebble mass throughout the simulations for [Fe/H] = 0.0. For all the simulations, the turbulent viscosity αturb = 10−4 is used, which ensures αturb ≪ αacc (however, see Sect. 3.2.1 for the cases using other values).
