SUMMARY:Building Planetary Systems: The Formation of Planetesimals\, A
 stronomy Colloquium\, Jake Simon\, Iowa State University
DESCRIPTION:Planetesimals are small rocky (and sometimes icy) objects\
 , typically 1-100 km in diameter (e.g.\, asteroids and comets in the S
 olar System). One of the largest unanswered questions in all of planet
 ary astrophysics is: how do these planetesimals form in the disks that
  orbit young\, newly forming stars (“circumstellar disks”)?  In th
 is talk\, I will discuss my group’s research projects devoted to ans
 wering this important question. I will first provide an overview of pl
 anet formation and describe how planetesimals are an integral step in 
 the planet formation process. I will then discuss the progress my grou
 p has made in understanding planetesimal formation with theoretical an
 d computational models. In particular\, by using computational fluid a
 nd particle dynamics\, run on large-scale supercomputing facilities\, 
 we are working towards understanding under what conditions and in what
  locations planetesimals can or cannot form in circumstellar disks. I 
 will conclude with a set of future goals to connect what we have learn
 ed so far to the larger picture of planet formation.
