Abstract
We present near infrared images of the bright rimmed globule IC 1396-N in t he H-2 2.12 mum narrow band filter as well as in broad band J, H and K filt ers. 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, indicati ng that they trace shocked regions along collimated stellar jets. From the H-2 knots morphology and orientation, we identify at least three different jets: one of them is driven by the young protostar associated with IRAS 213 91+5802, which represents the most luminous object in the region, while we were able to identify only one of the two other driving sources by means of near infrared photometry. Our photometry reveals the existence of a cluste r of young embedded sources located in a south-north line which follows the distribution of the high density gas and testifies for a highly efficient star formation activity through all the globule.
