Modeling of ALMA observations reveals diverse vertical heights for millimeter dust in six protoplanetary disks, from very thin in T Cha and PDS 111 to extended in DoAr 25, with models failing to match small dust distributions.
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.
