Ongoing star formation activity in the L1340 dark cloud.

Abstract (from CDS):

We present a study of the L1340 molecular cloud, which is known to be actively forming low- and intermediate-mass stars in three independent cores. We present optical and near-infrared images of the central regions of the three cores of this cloud, better known as RNO 7, RNO 8, and RNO 9. We show that RNO 7 is a Herbig Be cluster. We have discovered three Herbig-Haro flows in core A (southwestern part) of the cloud, named HH 487, 488, and 489. HH 487 is a spectacular set of bow shocks that appear to be driven by IRAS 02224+7227. HH 488A is a ∼3'.4-long flow possibly overlapping a second flow (HH 488B) in the line of sight. HH 489 is a flow extending to ∼1' on either side of the driving source IRAS 02249+7230. Most of these Herbig-Haro objects are found to be high-excitation objects.
