- Title
3D SPECTROSCOPY OF DWARF ELLIPTICAL GALAXIES.
- Authors
Sil'chenko, O. K.
- 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>8 Gyr, and the metallicities are subsolar.
