Abstract

We present near infrared images of the bright rimmed globule IC 1396-N in the H-2 2.12 mum narrow band filter as well as in broad band J, H and K filters. We detected several chains of collimated H-2 knots inside the globule, having different luminosities but similar orientations in the sky. Most of the knots are associated with peaks of high velocity CO emission, indicating that they trace shocked regions along collimated stellar jets. From theH-2 knots morphology and orientation, we identify at least three differentjets: one of them is driven by the young protostar associated with IRAS 21391+5802, which represents the most luminous object in the region, while wewere able to identify only one of the two other driving sources by means of near infrared photometry. Our photometry reveals the existence of a cluster of young embedded sources located in a south-north line which follows the distribution of the high density gas and testifies for a highly efficientstar formation activity through all the globule.
