Title: A deep X-ray observation of supernova remnant G304.6+0.1 (Kes 17) with Suzaku
Authors: F. Gok, A. Sezer

In this paper, we present the analysis of a deep (99.6 ks) observation of G304.6 + 0.1 with the X-ray Imaging Spectrometer on board Suzaku satellite. The X-ray spectral data are well-fitted with a plasma model consisting of a thermal component in collisional ionisation equilibrium and a non-thermal component. The thermal emission is well fitted with VMEKAL model with an electron temperature of kT_{e} ~ 0.75 keV, a high absorbing column density of N_{H} ~ 3.9 x 10^{22} cm^{-2} and near/lower solar abundances which indicate that the X-ray emitting plasma of G304.6 + 0.1 is dominated by swept-up ambient medium. The non-thermal component is well fitted with a power-law model with photon index of \Gamma ~ 1.4. We found a relatively high electron density n_{e} ~ 2.3f^{-½} cm^{-3}, age t ~ 1.4 x 10^4f^{½} yr, and X-ray emitting mass M_{x}~ 380f^{½} solar masses at an adopted distance of d=10 kpc. Using the morphological and spectral X-ray data, we confirm that the remnant is a new member of mixed-morphology supernova remnants.
