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''x150'', 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 1.2mm. The molecular clump is 0.45pc in radius and its mass and H₂ volume density are 310M_☉ and 1.2x10⁴cm^–3, respectively. Two overdensities were identified within the clump in HCN(3-2) and HCO⁺(3-2) lines. A comparison of the LTE and virial masses suggests that the clump is collapsing in regions that harbor young stellar objects. An analysis of the molecular lines suggests that they are driving molecular outflows.
