A giant Herbig-Haro flow from Haro 6-10

We report the discovery of a parsec-scale Herbig-Haro flow emanating from the young binary system Hare 6-10 in Taurus. The how extends for about 39' (1.6 pc) at a position angle of about 222 degrees and contains part of the previously known HH 184. The apparent ends of the flow are defined by the newly discovered III-I 410 and HH 411, which are located 24' southwest and 15' northeast, respectively, from Hare 6-10. We suggest that the giant HH flow is most likely driven by the infrared companion to the T-Tauri primary in Hare 6-10; however, the T-Tauri component also appears to be driving a relatively weak and much smaller outflow with a north-south orientation. The two flows appear to undergo synchronized episodes of increased mass ejection, which may be due to enhanced gravitational interactions between the binary components during periastron. We also report the discovery of a new I-II-I jet, III-I 414, which is driven by IRAS 04264+2433. HH 414 points directly toward an associated bow shock, HH 413; the HH 413/414 flow crosses the axis of the III-I 410/411 how at a large angle.
