Suzaku observation of supernova remnant G332.5-5.6

We analyse the Suzaku X-ray Imaging Spectrometer data of the central region of supernova remnant G332.5-5.6. The X-ray data are well described by a single non-equilibrium ionization thermal model, vnei, with an absorbing hydrogen column density of 1.4(-0.1)(+0.4) x 10(21) cm(-2). The plasma is characterized by an electron temperature of 0.49(-0.06)(+0.08) keV with subsolar abundances for O (0.58(-0.05)(+0.06) solar value) and Fe (0.72(-0.05)(+0.06) solar value) and slightly overabundance for Mg (1.23(-0.14)(+0.14) solar value). It seems that the central X-ray emission originates from a projection effect or evaporation of residual clouds inside G332.5-5.6. We estimate a distance of 3.0 +/- 0.8 kpc for G332.5-5.6 based on the extinction-distance relation. G332.5-5.6 has an age of 7-9 kyr.
