摘要：
We present the results of a near infrared high angular resolution study of young stellar objects. The observations have been carried out in 1993 and 1994 with the speckle camera SHARP 1 installed at the ESO-NTT. The sources were selected because of their known high degree of polarization at optical wavelengths, in order to search for disk-like extended structures. This paper only concentrates on the new multiple systems discovered. After a general presentation of the sample, each new system is presented individually. Then the relative reddening of the individual components as well as the possible link between the morphology of a system and its polarization are discussed.
