Revised photometric elements of the eclipsing systems BS Draconis and CD Tauri

  • 23 Accesses


The recently published two-colour photoelectric light curves of the double-lined spectroscopic binaries CD Tauri and BS Draconis have been analysed using the Wilson and Devinney (1971) method of solution. With respect to previous solutions, CD Tau shows small but appreciable differences, while for BS Dra the old elements are confirmed. The absolute elements, computed using Popper's spectroscopic data, show that both binaries have normal Main Sequence components, and the comparison of their relative radii with the Roche lobes allows us to classify them as geometrically detached.
