SUMMARY:Planet formation insights from debris disk dust and gas\, Astr
 onomy Colloquium\, Meredith Hughes\, Wesleyan University
DESCRIPTION:Debris disks are more massive analogs of our solar system'
 s Kuiper Belt\, and they trace the final assembly stages of planetary 
 systems.  The Atacama Large Millimeter/submillimeter Array (ALMA) has 
 provided sensitive\, high-resolution views of millimeter-size dust and
  molecular gas that allow us to trace the dynamics and chemistry of th
 is pivotal planet formation phase.  I will describe several recent obs
 ervations of gas and dust in debris disks with ALMA\, including a new 
 large program that will reveal how disk structures like rings and gaps
  evolve as the star settles onto the main sequence.
