摘要: We observed the south east (SE) limb of Cygnus Loop with Suzaku. Our spatially-resolved spectroscopic study shows that a one-kTe non-equilibrium ionization model represents our spectra fairly well. find metal abundances obtained are all depleted relative to solar values positional dependence along radial direction Loop. The in very edge show about half value, whereas other regions inside 0.2-times which has been believed be typical value for limb. “enhanced” abundance SE is quite similar found north-east (NE) Loop, and thus this another evidence an inhomogeneity radio map different feature: NE bright region, while almost no radio. Therefore, variation can not attributed non-thermal emission. as well depletion down 0.2 times still remain open question.
