Title: Inventory and Distribution of Disks, Protostars, and Proto-Brown Dwarfs in Young Stellar Clusters: Imaging with SQIID and SIRTF

Abstract: We propose wide-field (15' \times 15') SQIID JHK imaging of several young (< 1 Myr) stellar clusters targeted for our SIRTF GTO observations. These observations will be a key component in an IR/X- ray/millimeter-wave study of young stellar clusters within 1 kpc of the Sun, with the goals of: 1.) surveying each group and cluster to below the hydrogen burning limit, 2.) determining the 1-24 (micron) infrared spectral energy distribution (SED) for every star and protostar detected in each cluster, and 3.) using the SEDs to compare the star and planet formation properties in each region. The combined SQIID+SIRTF data will provide a complete inventory of circumstellar disks and protostars in our sample of young stellar clusters. SQIID data alone provide a census of brown dwarf candidates for spectroscopic follow-up, and a preliminary look at the spatial distribution of cluster members. SQIID is particularly important for the more distant clusters where a higher sensitivity is needed to detect deeply embedded sources. Because of weather and instrument difficulties, this project was not completed during time received in October 2002.
