Abstract:Spectrophotometric observations of the eclipsing binary system delta Capricorni, covering the wavelength interval lambdalambda3300–7300 Å, have been presented. Comparison of the standard spectral scans of delta Cap with the spectral scans of the stars of known spectral types and luminosity classes taken from the Breger (1976) catalogue shows that, near the phase of secondary eclipse, delta Cap shows the spectral-luminosity type as A8-9III. This is in agreement with the photometric findings of Srivastava (1987b). Hagr emission is not visible convincingly, however, some irregularities are apparent, at least in two scans, around the Hagr region.
