NEAR-INFRARED OBSERVATIONS OF SOUTHERN YOUNG MULTIPLE SYSTEMS

We report observational results from near infrared slit scanning of 16 southern pre-main sequence multiple sources. For each system, we deri ve the angular separation and the magnitude difference in the J, H, K and in most cases L bands. Two systems (Sz 30 and LkH alpha 346) are f ound to be triple and four (Herschel 4636, LkH alpha 346, RNO 92 and V V CrA) exhibit a flux inversion among the components between 0.55 and 3.61 mu m, that is, the secondary as defined in the visual begins to d ominate the system light at infrared wavelengths.
