Deep near-infrared images and ISOCAM observations of Chamaeleon I north

We present the results of deep near-infrared imaging and ISOCAM observation s of three selected regions localized in the northern part of the Chamaeleo n I dark cloud, in order to search for the low-luminosity population. In an area of 3 x 3 arcmin(2) centered on the bipolar molecular outflow, which i s the densest part of the cloud, we have discovered a new Class I source (h ere named ISOCAM-Cha INa2) with a spectral index alpha = 1.9 and 1-18 mu m luminosity of 0.6 L. that is most probably responsible for the observed CO outflow. The comparison between the observed K-magnitude distribution for t his region and that obtained for a region outside the outflow and adjacent to the star HD 97300 indicates the possible presence of a very low luminosi ty young stellar population in the densest part of the cloud.
