Abstract (from CDS):

We have carried out a wide-field survey for Herbig-Haro (HH) objects in nearby star-forming regions using the Beijing Astronomical Observatory 60/90 cm Schmidt telescope. The survey covered 56 deg2 in Perseus, Taurus, Orion, Monoceros, and other regions. Here we report our discovery of seven HH objects (HH 427-433) in the Barnard 1 dark cloud and one HH object (HH 426) in NGC 1333. The newly discovered HH objects demonstrate a great variety of morphological structures: HH 426, 429, and 432 each consist of two knots, HH 427 is a single knot, HH 428 is a bar, HH 430 is a jet, HH 431 is a bow shock-shaped patch, and HH 433 is a complex of four knots. HH 432A, 432B, and 433 constitute a giant, highly collimated jet with a projected linear size of ∼0.5 pc and a collimation ratio of ∼11. The jet aligns well with a nearby star, IRAS 03304+3100 (LkHα 327), and may be driven by this source. Two optically visible stars are supposed to be the exciting sources for HH 426 and 428. For HH 427, 429, and 430, no exciting source can be identified.
