Outcome of single-planet formation simulations with the default setting (i.e. (b, c) = (8, 3) for the Kelvin–Helmholtz timescale, [Fe/H] = 0.0, and the pebble accretion efficiency by IGM16) with α_turb = 10⁻³ (left panels),10⁻⁴ (middle panels), and 10⁻⁵ (right panels). The top panels show the final semi-major axis of a single planet for different initial semi-major axes and disc models. The bottom cells marked as ‘Init’ correspond to the initial semi-major axes that are common for all disc models. The bottom panels present the final planetary masses in log scale. The bottom cells represent the initial protoplanetary masses of 0.01M_⊕ for all the cases.
