The O abundance is the most important, since it is the most abundant element except H and He, and synthesized only by type II supernovae (SNe). In elliptical galaxies, an accumulation of stellar mass loss emit X-rays and therefore, the O abundance of the X-ray emitting gas reflects the stellar metallicity. Therefore, I propose to observe two elliptical galaxies, NGC 1404 and NGC 4374. and determine the O abundance of the gas with the RGS.
