DOIAbstract
Aims. We present an analysis of the region IRAS 08589−4714 with the aim of characterizing the molecular environment. Methods. We observed the 12CO(3 −2), 13CO(3 −2), C18O(3 −2), HCO+(3 −2), and HCN(3 −2) molecular lines in a region of 150′′× 150′′, centered on the IRAS source, to analyze the distribution and characteristics of the molecular gas linked to the IRAS source. Results. The molecular gas distribution reveals a molecular clump that is coincident with IRAS 08589−4714 and with a dust clump detected at 1.2 mm. The molecular clump is 0.45 pc in radius and its mass and H2 volume density are 310 M⊙ and 1.2 × 104 cm-3, respectively. Two overdensities were identified within the clump in HCN(3−2) and HCO+(3−2) lines. A comparison of the LTE...
