Spectrophotometry of speckle binary stars III

Abstract

Spectrophotometric observations of a third set consisting of 11 stars of speckle interferometric binaries are presented. Observations covered the range 3700-8400 Å, with a resolution of 18 Å. Results 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 catalogue and SIMBAD.
