Scientific paper

The paper describes observations of the CS (J = 1-0) emission, obtained with the high-resolution (10 arcsec) Nobeyama Millimeter Array and presents high-quality CO (J = 1-0) maps. The CS emission revealed a prominent V-shaped ridge or a ring around the S140 IR cluster encircling the blue and red lobes of the molecular outflow, with no emission detected in the vicinity of the IR sources. The observations suggest that the CS ring is a remnant of a nearly pole-on massive gaseous disk interacting with the high-velocity outflow.
