SUMMARY OF SEQUENCE NUMBER 800097
Title: THE ORIGIN AND DISTRIBUTION OF HEAVY ELEMENTS IN THE COMPACT GROUP HCG 62
Observer: VRTILEK
Subject Category: Clusters of Galaxies
Seq: 800097 ObsId: 00921
Long-term Plan bin: 23-Jan-2000
ABSTRACT
Most galaxies in the present-day Universe are in compact groups and poor clusters. Groups are thought to be the building blocks from which clusters formed, and they accordingly occupy an important place in the continuum between isolated galaxies and rich clusters. We propose an observation of the compact group HCG 62 with ACIS-S (BI); our purpose is the accurate determination of the abundances of heavy elements as a function of position in the group. This observation exploits the high X-ray brightness of this group and --- with only four members --- its sparseness to understand the relatively low overall metallicity of the intragroup gas, to test whether any abundance variations are associated with individual galaxies, and to trace the origin of the enrichment to type Ia or II SNs.
