Solids surface density profiles Σ in the V883 Ori disk at three different points in time. Left: before the outburst, the snow line was located at around 2 au. In the domain plotted above the drifting pebbles consist of ices and silicates. Middle: during the outburst, the snow line has moved to ~50 au, exterior to which the pebbles still contain water ice and silicates. The surface density profile of icy pebbles is given by the blue line. Interior to ~50 au the pebbles have disintegrated and smaller silicate particles remain (red line). We expect that the V883 Ori disk is presently in this state. Right: assuming that the disk temperature remains at T_post after the outburst, eventually a pileup of silicate particles interior to the snow line (red lines) is realized owing to their smaller drift velocity. There is also a pileup in the icy pebble surface density distribution (blue lines) owing to outward diffusion and re-condensation (Schoonenberg & Ormel 2017). The dashed lines correspond to the situation after 10⁴ yr and the dotted lines correspond to the steady-state solution. The solid lines are the same as in the middle panel. Since the typical decay timescale of an FU Ori outburst is ~100 yr, we do not expect to reach either of these states.
