		| Abstract: | 
		HB9 (G168.0+2.6) is a mixed morphology SNR. Ginga observation of HB9 found hard X-ray emission above 1.5 keV.  Although it is suggested that its origin is Radio Galaxy 4C + 46.09, intra cluster gas, or X-ray emitting plasma associated with HB9, it is not concluded. Using data obtained with Suzaku, we conducted a detail spectral study of the central region of HB9.  HB9 has almost no hard X-ray emission above 2 keV.  In order to investigate the ionization state of plasma associated with HB9, we fitted the spectra with a plasma model and conclude that plasma is the non-equilibrium ionization state with a thermal temperature of ∼0.7 keV.  In this paper, we report the results and discuss type of explosion based on the abundance ratio. |
