| 英文摘要 | Taking the advantage of the large field of view at the 60/90 cm Schmidt telescope of Beijing Astronomical Observatory, we were able to carry out a wide-held survey of Herbig-Haro (HH) objects in nearby star-forming regions, including Perseus, Taurus, Orion, and others. In a 58' x 58' field centered on NGC 2068 and NGC 2071 (M78), two active regions of star formation in the giant molecular cloud complex L1630, we found 17 HH objects exhibiting prominent [S II] emission but without continuum emission. Among these, we confirmed all the 11 known HH objects listed in the General Catalogue of Herbig-Haro Objects in this field. In addition, we discovered another six new HH objects, including HH 437, 438A-C, 440A/B, 442, 443, and 452A/B. These objects exhibit a variety of morphological structures, from knot to nebula. The discovery of these HH objects demonstrates strong activity of young stellar objects in the region we are studying. The large-scale spatial distribution of HH objects in the region is discussed by combination of our results and previous data. |
