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 ratio q = mc[mh = 0.6. This solution differs somewhat from that obtained by Giuricin et al. (1980), using Wood's (1972) method, but seems more realistic because of the smaller value of q and the reduced temperature difference between the components, which amounts to about 3300 K.

Abstract

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 ratio q = mc[mh = 0.6. This solution differs somewhat from that obtained by Giuricin et al. (1980), using Wood's (1972) method, but seems more realistic because of the smaller value of q and the reduced temperature difference between the components, which amounts to about 3300 K.
