Abstract

Some results of 3D spectroscopy for a small sample of dwarf elliptical galaxies are presented. By measuring Lick indices and investigating radial profiles of the SSP-equivalent ages and metallicities of the stellar populations, I have found evolutionary distinct cores in all of them. The ages of these cores are 2–4 Gyr, and the metallicities are higher than the solar one. Outside the cores, the stellar populations are typically old, T > 8Gyr, and the metallicities are subsolar.
