摘要：
We make a detailed measurement of the metal abundance profiles and metal abundance ratios of the inner core of M87/Virgo observed by XMM-Newton during the performance veri cation phase. We use multi-temperature models for the inner regions, and we compare the plasma codes APEC and MEKAL. We confirm the strong heavy-element gradient previously found by ASCA and BeppoSAX, but also find a significant increase in light elements, in particular O. This fact, together with the constant O/Fe ratio in the inner 9', indicates an enhancement of contribution in the core of the cluster, not only by Type Ia supernovae but also by Type II supernovae.
