Scientific paper

Photometric data for the components of 10 widely separated common proper motion systems, about half of which are probable Local Association members, are discussed with attention to the ages of individual stars. Local Association system components exhibit the same mixture of ages which occurs in clusters of the association. The importance of further astrometric observations is noted for the cases of the systems AR Cas and Alpha Eri. It is assumed that the former system contains at least five stars, A, C, F, G and the spectroscopic companion of A, with the best radial velocity estimate being obtained from star C.
