Resumen:
We analyze the distribution of the molecular gas associated with IRAS 10349-5824, a young stellar object located on the edge of the HII region Gum 31, with the aim of investigating the existence of bipolar outflows. We use CO(2-1) line observations obtained with the APEX telescope, H_2 line observations on the K band taken with Flamingos 2 in Gemini South and additional data from Spitzer at 4.5, 8 and 24 microns.WISE J103648.97-584010.7 (WISE 1), classified as class II, coincides with extended emission in 4.5 microns, suggesting the presence of bipolar flows, and with H_2 emission at 2.12 microns. Three extended sources detected in H_2 at 0.50 and 1.50 arcmin of WISE 1 could also suggest the presence of shocked gas. Additional evidence of bipolar outflows comes from CO spectra.
