Scientific paper

We propose to observe two elliptical galaxies containing hot gas which were found to have very low metal abundances (<0.1 solar) in previous ROSAT and ASCA analyses. The stellar metallicities of these two ellipticals are normal, being 1-2 times solar at their centers, or ten times greater than the gaseous abundances. Chandra ACIS observations will allow us to determine whether the gaseous abundances are really this low and provide a spatially resolved comparison between gaseous and stellar metallicities.
