Minimum pebble flux that is required for the thermal torque to become positive in ME /year for different times. It generally drops in time and is high in the inner and outer disk. At a few AU there is a sweet spot, caused by the critical thermal diffusivity. As the thermal critical mass is only an estimate as of yet, values above are still plotted here. For a more comprehensive review of these plots see Fig. 5.
