AI Cru: A semi-detached system?

The only existing photoelectric light curve of AI Cru has been re-analysed using the Wilson and Devinney (1971) direct method of solution. The system is found to be a semi-detached system of spectral type (B5 v+B8 v), with a mass ratioq=m_c/m_h=0.6. This solution differs somewhat from that obtained by Giuricinet al. (1980), using Wood's (1972) method, but seems more realistic because of the smaller value ofq and the reduced temperature difference between the components, which amounts to about 3300 K.
