Popis: | Stromgren and Hβ photometry of 38 stars in the field of Ara OB 1 is presented. The excesses, the absolute magnitudes and the temperatures of the stars have been obtained. The masses and the ages are also estimated, based on the models of Maeder & Meynet (1988, A&AS, 76). Two different groups have been distinguished by their space locations at V 0 −M V = 10.23 and 12.01 mag (assuming a normal extinction law). The more distant group is younger and more massive. The magnitude and the excess of the WR star MR62 point to its probable membership of this group |
