The Nature of the Driving Source of the HH30 Jet/Counterjet System

The Herbig-Haro object 30 (HH30) is located in the L1551 dark cloud, at a distance of about 140 parsec, in the Taurus star-forming region. HH30 is considered a prototypical jet-disk
system driven by a young stellar object (YSO). The impressive jet/counterjet structure extends several arcminutes in both directions from the exciting source, and shows an undulating morphology
in the narrow-band [SII] images. Astronomers using ACAM at the William Herschel Telescope have been able to obtain a deep image of the HH30 field and have found an
interesting explanation for the jet/counterjet system.
