We carried out observations of the central and 20' east offset regions of the
cluster of galaxies Abell 1060 with Suzaku. Spatially resolved X-ray spectral
analysis has revealed temperature and abundance profiles of Abell 1060 out to
27' ~ 380; /h_70 kpc, which corresponded to ~ 0.25; r_180. Temperature decrease
of the intra cluster medium from 3.4 keV at the center to 2.2 keV in the
outskirt region are clearly observed. Abundances of Si, S and Fe also decrease
by more than 50% from the center to the outer, while Mg shows fairly constant
abundance distribution at ~ 0.7 solar within r < 17'. O shows lower abundance
of ~ 0.3 solar in the central region (r~ 6'), and indicates a similar feature
with Mg, however it is sensitive to the estimated contribution of the Galactic
components of kT_1 ~ 0.15 keV and kT_2 ~ 0.7 keV in the outer annuli (r ~ 13').
Systematic effects due to the point spread function tails, contamination on the
XIS filters, instrumental background, cosmic and/or Galactic X-ray background,
and the assumed solar abundance tables are carefully examined. Results on
temperature and abundances of Si, S, and Fe are consistent with those derived
by XMM-Newton at r < 13'. Formation and metal enrichment process of the cluster
are discussed based on the present results.Comment: 20 pages, 19 figures, accepted for publication in PAS
