Scientific paper

During the first four years of Spitzer's mission, we have conducted a comprehensive IRS survey of disks around stars and brown dwarfs in nearby star-forming regions through the IRS GTO program. We are using these data to study several aspects of circumstellar disks and planet formation, including the settling, composition, size distribution, and crystallization fraction of dust and the presence of gaps and inner holes. The two primary cornerstones of this survey are Taurus and Chamaeleon I, which are the two nearest and best-studied star-forming regions. We propose to obtain IRS spectra of all of the remaining disk-bearing stars and brown dwarfs in these regions that have not been observed with IRS. With the completion of this program, Taurus and Chamaeleon I will be the most thoroughly surveyed star-forming regions with IRS.
