A22 (2011) Abstract:We perform a detailed investigation of
sources from the Cold Cores Catalogue of Planck Objects (C3PO).
Our goal is to probe the reliability of the detections, validate
the separation between warm and cold dust emission components,
provide the first glimpse at the nature, internal morphology and
physical characterictics of the Planck-detected sources. We
focus on a sub-sample of ten sources from the C3PO list,
selected to sample different environments, from high latitude
cirrus to nearby (150pc) and remote (2kpc) molecular complexes.
We present Planck surface brightness maps and derive the d
