SUMMARY:Sizing up Protoplanetary Disks\, Astronomy Colloquium\, Leon T
 rapman\, UW Madison
DESCRIPTION:Although we are certain that planets can be formed\, there
  are still large gaps in our understanding of how they formed. Observa
 tions show that exoplanets are found in a large variety of planetary s
 ystems\, from multiple terrestrial planets packed inside the central ~
 1 AU to several gas giants spread over tens of AU from the central sta
 r. The diverse outcomes of planet formation are intimately linked to t
 he disks of gas and dust around young stars\, called protoplanetary di
 sks\, in which these planets have formed and grown. How much material 
 do these disks contain for planet formation? Is this material concentr
 ated close to the star or spread over a large area? And how do the gas
  and dust that make up the disk evolve over time?
\nIn my talk I will 
 show how studying bulk properties of protoplanetary disks\, especially
  their size\, can answer these questions and help us solve the riddle 
 of planet formation.
