HD 138168 and HD 138181, a hard binary?
Relevant physical data for the two F3 stars HD 138168 and HD 138181,which form a typical instance of apparent intermediate configurationbetween double star and cluster, are compared to determine the possibleexistence of significant individual properties. Very little differenceis found between the two stars. The average line depth for HD 138181shows an excess of about three percent in relation to the depth for HD138168, possibly indicating a slight difference in temperature orrotational velocity.

Concluding observations of loose stellar clusterings in the southern Milky Way
UBV photometry and spectral classification have been performed on 280stars in the Carina-Crux-Centaurus-Norma region, suspected of belongingto poor open clusters or associations. The work is a concluding part ofa large project for detecting and listing of such objects in order toobtain an improved concept about the true frequency of clusterings inthe Milky Way. The result indicates that a majority of the suspectedobjects are members of various types of physical stellar clusterings,occasionally cluster remnants.
