THE STRUCTURE OF THE HALO OF THE STAR CLUSTER NGC-2070

The structure of the halo of the star cluster NGC 2070 in the Large Ma gellanic Cloud is investigated on the basis of published magnitudes an d positions of its stars. The cluster halo has been found to be compos ed of a large number of stellar subclusters (about 30) having from 10 to 150 stars. In most cases, the subclusters appear as filaments or ar cs; they form ring-shaped structures, 10 - 20 pc in diameter, that coi ncide with ionized-gas filaments in the central part of the Tarantula nebula. The color-magnitude diagrams for the subclusters reveal a poss ible difference in age. The subclusters differ in stellar composition: the farther the subgroup from the cluster center, the lower the upper limit on the brightness of its stars. This can be explained either by the difference in the age of the subclusters or by a difference in th e physical conditions in the original gas cloud.
