Follow-up observations of Planck cold clumps in ${}^{12}$CO/${}^{13}$CO/C${}^{18}$O (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 (\cite[Planck Collabrators et al. 2011]{Planck_etal11}). To study their properties, we have carried out a molecular line (${}^{12}$CO/${}^{13}$CO/C${}^{18}$O) survey towards 674 Planck cold clumps in the ECC with the PMO 13.7 m telescope.
