Spatial distributions of various disk characteristics just before the onset of the burst at t = 90 kyr (model 1, top row) and t = 290 kyr (model 2, bottom row) after the disk formation instance. Columns from left to right represent the gas surface density, grown dust surface density, small dust surface density, temperature, maximumdust size, Stokes number, and the mass fraction of water ice on dust grains , respectively. The green lines outline the position of the H₂O snowline.
