Scientific paper

Waelkens and Rufener's (1983) photoelectric lightcurve (as yet unexplored) of the newly discovered eclipsing binary HR 7464 has been analyzed. The photometric solution presented here reveals that this binary is an A5m + G main sequence detached system, which is particularly remarkable for the great dissimilarity between its members. The frequency of detached eclipsing pairs with very unequal members (i.e., with low mass ratio) is then discussed; some bimodality in the innate mass ratio distribution of close binaries is inferred.
