Abstract

Infrared speckle-masking observations of eleven binary systems with the 6-m Special Astrophysical Observatory telescope are presented. A resolution of 43 mas in J (1.25 µm) and 76 mas in K (2.2 µm) has been achieved in reconstructed images. Accurate magnitude differences, separations, and position angles have been determined for all the resolved binaries. The pair HR 1071 with an abnormally low lithium abundance is considered in more detail.
