A COMMENT ON THE COLORS OF GLOBULAR CLUSTERS IN ELLIPTICAL GALAXIES.

Abstract

The globular clusters in the Local Group dwarf elliptical galaxies tend to be bluer than the halos of their parent galaxies, by the same amounts (Δ(B-V) ≅ 0m.15, Δ(U-V) ≅ 0m.3) as for the clusters in M87 and other large Virgo ellipticals. This characteristic, when added to the other properties of globular-cluster systems discussed currently, is more consistent with the view that the observed differences (mean color, space distribution, metallicity gradient and dispersion) between the halo stars and the globular clusters themselves were "built in" by distinct formation epochs, rather than acquired later by environmental processes.
