Follow-up observations of Planck cold clumps in 12CO/13CO/C18O (1--0) transitions
Abstract
The Planck Early Cold Cores Catalog (ECC) provides an unbiased list of Galactic cold clumps, which form an ideal sample for studying the early phases of star formation ([Planck Collabrators et al. 2011]Plancketal11). To study their properties, we have carried out a molecular line (12CO/13CO/C18O) survey towards 674 Planck cold clumps in the ECC with the PMO 13.7 m telescope.
