 note = {The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We have discovered a three-dimensional onion-like metallicity structure in Tychoapos;s SNR using Suzaku, in such a way that iron is more concentrated in the remnant center than intermediate-mass elements (IMEs: Si, S, Ar, and Ca). This is achieved by measuring widths of the emission lines of those elements as a function of the angular distance from the center of the remnant. We interpret our results as representing Doppler broadening caused by a line-of-sight velocity dispersion of the line-emitting ions. Applying two Gaussian models (red- and blue-shifted components) to each broadened line, we determine the expansion velocities of the IMEs and Fe as approximately 4900 km s(exp -1) and approximately 3800 km s(exp -1), respectively. Combining our results with the projected image of the SNR, we successfully construct a three-dimensional onion-like structure of the SNR., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574022, レポート番号: JAXA-SP-09-008E},
