Spectrophotometry of speckle binary stars

Abstract

Spectrophotometric observations of 20 speckle interferometric binary stars in the wavelength range 3640-8340 Å, with a resolution of 18 Å, are presented in the form of the measured flux corrected for atmospheric extinction in the units of erg/cm²\cdot s \cdot Å, with no corrections for interstellar reddening. B,V, and R magnitudes, B-V colour indices and entire spectral types are also presented and compared with those of Hipparcos and Tycho catalogues and SIMBAD.
