摘要：
We have measured the radial light profiles of the five brighter clusters in the Fornax dwarf elliptical galaxy. We find that the clusters fall into two structural groups. Hodge clusters Nos. 1 and 2 have similar core radii which are twice the core radii of clusters Nos. 3, 4, and 5. Clusters Nos. 1 and 2 appear to fit truncated King models. Clusters Nos. 3, 4, and 5 do not fit the King models but show an extended halo structure with no evidence of tidal truncation. We conjecture that clusters Nos. 1 and 2 have interacted dynamically with each other while the other clusters have had no such interaction over their lifetime.
