Spectrophotometric observations of Delta Capriconi

Abstract

Spectrophotometric observations of the eclipsing binary system δ Capriconi, covering the wavelength interval λλ3300-7300Å, have been presented. Comparison of the standard spectral scans of δ Cap with the spectral scans of the stars of known spectral types and luminosity classes taken from the Berger (1976) catalogue shows that, near the phase of secondary eclipse, δ Cap shows the spectral-luminosity type as A8-9III. This is in agreement with the photometric findings of Srivastava (1987b). Hα emissions is not visible convincingly, however, some irregularities are apparent, at least in two scans, around the Hα region.
