Stellar populations of dwarf elliptical galaxies from high-resolution, optical spectroscopic data

Instituto de Astrof´isica de Canarias, V´ia L´actea s/n, 38200 La Laguna, Tenerife, Spainemail: cenarro@iac.esAbstract. We present some preliminary results obtained within the MAGPOP-ITP collabora-tion for a subsample of four dwarf elliptical galaxies. On the basis of high-resolution, opticalspectroscopic data obtained for these galaxies at the WHT, their ages, metallicities and singleelement abundance ratios have been derived from their line-strength indices and the improved,MILES-based, stellar population model predictions by Vazdekis
