Overview

C2D used all three Spitzer instruments (IRAC, MIPS, and IRS) to observe sources that span the evolutionary sequence from molecular cores to protoplanetary disks, encompassing a wide range of cloud masses, stellar masses, and star-forming environments. In addition to targeting about 150 known compact cores, C2D surveyed with IRAC and MIPS (3.6-70 microns) the entire areas of five of the nearest large molecular clouds for new candidate protostars and substellar objects as faint as 0.001 solar luminosities. C2D also observed with IRAC and MIPS about 190 systems likely to be in the early stages of planetary system formation (ages up to about 10 Myr), probing the evolution of the circumstellar dust, the raw material for planetary cores. If you use C2D data, please cite the journal articles Evans et al. (2003) and Evans et al. (2009) for the set, along with Enoch et al. (2007) and Enoch et al. (2009) for the Bolocam survey as well as the dataset Digital Object Identifier (DOI): 10.26131/IRSA421. Jump to documentation.
