Abstract
We analyze the 160 micron emission in the 44 sq deg Taurus Spitzer Legacy Survey to produce a mosaic of the cold dust distribution. The analysis shows there are two main emission components: the extended cold cloud at 14.2K, and knotty filaments of cold cores at ~10K. The distribution of 160 micron cold cores is similar to the 2mass extinction map, but has higher 1 arcmin spatial resolution. We further compare the distribution of cold cores with YSOs that have strong disk emission at 70 micron. In this sample 90 percent of class I sources and 55 percent of class II sources are spatially coincident with a cold core. However, most cold cores in Taurus are starless.
