AbstractThe physical and chemical properties of cold and dense molecular clouds are key to understanding how stars form. Using the IRAM 30 m and NRO 45 m telescopes, we carried out a Multiwavelength line-Imaging survey of the 70 mu m-dArk and bright clOuds (MIAO). At a linear resolution of 0.1-0.5 pc, this work presents a detailed study of parsec-scale CO depletion and HCO(+)deuterium (D-) fractionation toward four sources (G11.38+0.81, G15.22-0.43, G14.49-0.13, and G34.74-0.12) included in our full sample. In each source withT n(H) similar to 10(4)-10(5)cm(-3), we compared pairs of neighboring 70 mu m bright and dark clumps and found that (1) the H(2)column density and dust temperature of each source show strong spatial anticorrelation; (2) the spatial distribution of CO isotopologue lines and dense gas tracers, such as 1-0 lines of H(13)CO(+)and DCO+, are anticorrelated; (3) the abundance ratio between (CO)-O-18 and DCO(+)shows a strong correlation with the source temperature; (4) both the (CO)-O-18 depletion factor and D-fraction of HCO(+)show a robust decrease from younger clumps to more evolved clumps by a factor of more than 3; and (5) preliminary chemical modeling indicates that chemical ages of our sources are similar to 8 x 10(4)yr, which is comparable to their free-fall timescales and smaller than their contraction timescales, indicating that our sources are likely dynamically and chemically young.
