Herbig-Haro outflows in the V380 Orionis region.

CORCORAN D. and RAY T.P.

Abstract (from CDS):

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 some newly found Herbig-Haro (HH) objects, appears to delineate a poorly collimated optical outflow from this source. The optical outflow complements a redshifted molecular outflow to the east of V 380 Ori implying an overall east-west outflow axis. Although V 380 Ori is classified as a Herbig Ae/Be (HAEBE) star, it shows LiIλ6708 in absorption suggesting the additional presence of a T-Tauri star. In this regard, it is interesting that Leinert et al. (1994), using near-infrared speckle 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 were investigated, HH130 and the newly discovered HH147. The bow-shaped HH130 was previously thought to be an isolated object but we show here that it is part of an extended (>0.7pc) outflow and demonstrate that it could be driven by a ``light" jet. HH147 is particularly interesting in that its source, a T-Tauri star, is found to exhibit a P-Cygni profile in Hα. HH147 itself appears to contain both highly and poorly collimated outflow components.
