Scientific paper

The paper presents IR speckle observations of SR-12 and Rox 31, two subarcsec premain-sequence binaries in the Rho Ophiuchi dark cloud (distance 160 pc). The present IR speckle observations which were carried out in two orthogonal scan directions and in two IR bandpasses added the following information to the lunar occultation data: (1) the 'true' separation projected on the sky, (2) the position angle of the binaries, and (3) the H-K color of the individual components (of SR-12 only). An analysis is presented of lunar occultation versus speckle observations.
