Abstract
With the advent of speckle interferometry and similar techniques, it has been possible to obtain orbital data, and, thereby, masses for a number of binary stars which were higherto unresolvable. For the full astrophysical exploitation of this benefit, it then becomes essential to obtain photometric and spectrophotometric information on these systems. Photometry can often be secured by extensions of the basic speckle resolution technique, and several solutions have been proposed for the problem of obtaining uncontaminated spectra of the normally blended stellar components such as objective prism speckle spectroscopy and wideband projection speckle spectroscopy, and passive interspectroscopy. We present here further practical development of the methods suggested in Paper I and the results of some observational tests of the technique.
