A deep X-ray observation of supernova remnant G304.6+0.1 (Kes 17) with Suzaku

Abstract

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 {\it Suzaku} satellite. The X-ray spectral data are well-fitted with a plasma model consisting of a thermal component in collisional ionization equilibrium and a non-thermal component. The thermal emission is well fitted with VMEKAL model with an electron temperature of $k{T}_{\mathrm{e}}\sim 0.75$ keV, a high absorbing column density of $N_{\mathrm{H}}\sim 3.9\times 10^{22}$ $\mathrm{c}{\mathrm{m}}^{-2}$ 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 $\Gamma \sim 1.4$. We found a relatively high electron density $n_{\mathrm{e}}\sim 2.3f^{-1/2}$ cm${}^{-3}$, age $t$ $\sim 1.4\times 10^4{f}^{1/2}$ yr, and X-ray emitting mass $M_{\mathrm{x}}\sim 380f^{1/2}$ {M\sun} 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.
