HERBIG-HARO OUTFLOWS IN THE V-380 ORIONIS REGION

We report the discovery of a remarkable emission line ''loop'' to the west of V 380 Ori. This ''loop'', taken together with the known and so me newly found Herbig-Haro (HH) objects, appears to delineate a poorly collimated optical outflow from this source. The optical outflow comp lements a redshifted molecular outflow to the east of V 380 Ori implyi ng an overall east-west outflow axis. Although V 380 Ori is classified as a Herbig Ae/Be (HAEBE) star, it shows LiI lambda 6708 in absorptio n suggesting the additional presence of a T-Tauri star. In this regard , it is interesting that Leinert et al. (1994), using near-infrared sp eckle interferometry, have recently found V 380 Ori to be a double. It seems unlikely, however, that the T-Tauri star is responsible for the outflow. In the area around V 380 Ori, two other optical outflows wer e investigated, HH 130 and the newly discovered HH 147. The bow-shaped HH 130 was previously thought to be an isolated object but we show he re that it is part of an extended (greater than or similar to 0.7 pc) outflow and demonstrate that it could be driven by a ''light'' jet. HH 147 is particularly interesting in that its source, a T-Tauri star, i s found to exhibit a P-Cygni profile in H alpha. HH 147 itself appears to contain both highly and poorly collimated outflow components.
