An optimal Stokes number window of 0.01-0.03 allows streaming instability to form planetesimals and pebble accretion to build all three main planet classes, with cold gas giants needing the lowest turbulence and largest discs.

Simulations require 2000 Earth masses of pebbles to match observed disc gaps, but this produces mostly gas giants and few super-Earths, contradicting exoplanet data.

Exploring the conditions for forming planetesimals by the streaming instability and planetary systems by pebble accretion
An optimal Stokes number window of 0.01-0.03 allows streaming instability to form planetesimals and pebble accretion to build all three main planet classes, with cold gas giants needing the lowest turbulence and largest discs.

Are the observed gaps in protoplanetary discs caused by growing planets?
