Figure 1. Map of collisional outcome in the disk. The sizes of colliding particles are reported on the axes. The colors denote the result of each pair-wise collision. Green denotes growth, red denotes erosion, and yellow denotes neither of the above (i.e., a bounce). The label S stands for sticking, SB for stick and bounce, B for bounce, MT for mass transfer, E for erosion, and F for fragmentation. This map is computed for compact (silicate) particles, at 3 AU.
