... High-resolution Near-infrared Study of the Deeply Embedded Young Stellar Object S140 IRS 3 . ... P22P We explore the structures immediately surrounding the high-mass young stellar object S140 IRS 3 within the L1204 molecular cloud. ... The S-shaped structure of this feature can be well reproduced by a model assuming a precessing outflow from IRS 3a. Furthermore, we find several elongated features pointing away from IRS 3 in a southern direction. ...
