SUMMARY:The disks of dawn: setting the stage for the formation of planetar
 y systems - Leonardo Testi (ESO)

DESCRIPTION:Circumstellar disks appear in the early phases of formation of
  stars and play a key role in the assembly of the final mass of the centra
 l star and in the possible formation of a planetary system around it. I wi
 ll review our understanding of the properties and evolution of disks aroun
 d young stellar objects\, focusing on the solids (dust and pebbles) in dis
 k. The evolution of the solids is directly related to the initial stages o
 f planets formation as grains are expected to grow to large pebbles and fo
 rm first planetesimals and then rocky cores of planets. I will discuss the
  current observational evidence for grain evolution in disks\, the difficu
 lties and successes of theoretical models to explain observations and the 
 latest ideas on grain populations segregation in disks. I will discuss fut
 ure observational tests\, in particular with ALMA Early Science and beyond
 \, that will allow us to pose tighter constraints on models of solids evol
 ution in disks.
