Bipolar Outflow from S140 IRS 1 Hayashi, M. ; Hasegawa, T. ; Omodaka, T. ; Hayashi, S. S. ; Miyawaki, R. Abstract The molecular cloud in the vicinity of the infrared sources adjacent to the S140 H II region was observed in 12CO and 13CO emission with an angular resolution of 16arcsec. These observations demonstrate that the high-velocity flow observed in the S140 molecular cloud has a bipolar nature. The blue- and red-wing components are offset by 35arcsec (0.15 pc), being symmetrical with respect to IRS 1. The most probable driving source of this bipolar outflow is S140 IRS 1, the most luminous infrared object in this region. The dependence of the mass and the kinetic energy on velocity is derived for the molecular outflow, based on the column density of molecular hydrogen per unit velocity interval and the effective emitting area.
