C2D Full CORES Catalog

The Cores to Disks (C2D) Spitzer Legacy Program 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, it surveyed with IRAC and MIPS (3.6-70 mum) 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 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. The Full CORES Catalog provides the most complete but least reliable list of sources in the C2D CORES fields (82 small cloud cores). This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.

核至盘（Cores to Disks，简称C2D）斯皮策遗产项目使用斯皮策望远镜的三台仪器（IRAC、MIPS与IRS），对覆盖从分子云核到原行星盘演化序列的天体开展观测，涵盖了多样的云团质量、恒星质量与恒星形成环境。除靶向观测约150个已知致密云核外，该项目还利用IRAC与MIPS（3.6~70微米）对5个距离最近的大型分子云的全区域开展巡天，以搜寻新的原恒星候选体与亚恒星天体，探测极限可达0.001倍太阳光度。C2D项目利用IRAC与MIPS观测了约190个大概率处于行星系统形成早期阶段（年龄最高约10百万年）的天体系统，以此探究作为行星核形成原料的星周尘埃的演化过程。完整云核目录（Full CORES Catalog）收录了C2D云核天区（包含82个小型云核）中数量最全面但可靠性相对最低的天体列表。本数据集及相关服务由加州理工学院依据与美国国家航空航天局签订的运营合同负责运营的IPAC旗下红外科学档案库（Infrared Science Archive，简称IRSA）提供。
