	Deuterium Fractionation as an Evolutionary Probe in Massive Protostellar/Cluster Cores Deuterium fractionation, D_frac, vs. gas temperature (panel a), fitted line width (panel b), and CO depletion factor (panel c) in a number samples of massive star forming regions. ...(more)
	First detection of HC3N in protoplanetary disks The cyanoacetylene (HC3N) is a precursor of the organic molecules. It was observed for the first time in three protoplanetary disks thanks to IRAM 30m and PdBI observations. HC3N is ...(more)
	The 7 mm Continuum Image of the Binary Protostellar System L1551 IRS 5 The 7 mm continuum image of the binary protostellar system L1551 IRS 5 obtained with the VLA (Lim and Takakuwa 2006, ApJ, 653, 425). ...(more)
	Carbon-chain and Organic Molecules around Very Low Luminosity Protostellar Objects of L1521F-IRS and IRAM 04191+1522 Molecular-line spectra toward L1521F (left) and IRAM 04191+1522 (right). Spectra from molecules such as C3H2, CH3CCH, and C4H, so-called "carbon-chain" molecules, are more intense in L1521F than in IRAM 04191+1522. ...(more)
	Rotating Gas Motion around Protostars Morphology (contour) and kinematics (color scale) of envelopes around a sample of Class 0 and I protostars seen in the C18O (2-1) emission observed with the SMA. The color scale ...(more)
