A high-velocity molecular outflow from the G9.62+0.19 star-forming region.

Abstract (from CDS):

We have observed the G9.62+0.19 region of massive star formation with the IRAM 30 m single-dish telescope in the HCO+(1-0), SO(43-32), and SiO(5-4) spectral lines, and with the IRAM Plateau de Bure interferometer in the 3 mm continuum and the HCO+(1-0) and CH3OH(153-144) A spectral lines. We detect a high-velocity molecular ouflow with a total velocity extent of at least 60 km.s–1. The orientation of the outflow axis is very close to the line of sight. Our estimates of the mass and energetics of the outflowing gas indicate that a massive object must be responsible for driving the flow, with the hot core region G9.62+0.19 F as the most likely candidate. We also detect emission from hot methanol coincident with the position of continuum component E, but CH3OH(153-144) A is not detected at the position of the G9.62+0.19 F hot core region.
