Synthetic photometry of speckle interferometric binaries

Abstract

The synthetic magnitudes and color indices of 46 speckle interferometric stars have been computed depending on their observational spectral energy distributions. The Strömgren vby and Tycho BV passbands have been used to calculate magnitudes of the systems. These data when combined with the magnitude differences of the sub-components from speckle interferometry observations will allow the finding of the parameters of the individual components. These parameters will improve our knowledge about binary system formation and evolution.
