Scientific paper

I review the observed properties of dust in the disks around pre-main sequence stars, with a focus on two specific aspects. The first is the evidence of vertical sedimentation of grains, with smaller particles (polycyclic aromatic hydrocarbons (PAHs)) on the surface and larger grains closer to the midplane. The second is the evidence of a substantial mass of very large grains (millimeter to centimeter size: 'pebbles') in the outer regions of a number of disks. While the observations are in general agreement with grain growth by collisional coagulation, many details, and the presence of 'pebbles' in particular, still need to be understood.
