Abundance Ratios in Dwarf Elliptical Galaxies
- 1. Univ Groningen, Kapteyn Astron Inst, POB 800, NL-9700 AV Groningen, Netherlands
Description
The aim of this study is to determine abundance ratios and star formation histories (SFH) of dwarf ellipticals in the nearby Virgo cluster. We perform a stellar population analysis of 39 dEs and study them using index-index and scaling relations. We find an unusual behaviour where [Na/Fe] is under-abundant w.r.t. solar while [Ca/Fe] is over-abundant.
