A giant Herbig-Haro flow from Haro 6-10

We report the discovery of a parsec-scale Herbig-Haro flow emanating from t he 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 p reviously known HH 184. The apparent ends of the flow are defined by the ne wly 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 flo w 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 rel atively weak and much smaller outflow with a north-south orientation. The t wo flows appear to undergo synchronized episodes of increased mass ejection , which may be due to enhanced gravitational interactions between the binar y 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 directl y toward an associated bow shock, HH 413; the HH 413/414 flow crosses the a xis of the III-I 410/411 how at a large angle.
