Scientific paper

The supernova remnants G 327.1-1.1 and G 327.4+0.4 (Kes 27) are located 1.5° apart in the galactic plane in the constellation Norma. Lamb and Markert (1981), using the Einstein IPC, discovered that both were irregular, filled-center X-ray sources with possible point sources superposed. ROSAT PSPC observations now map the diffuse structure and clearly show the unresolved sources in each field. As expected, the spectra are relatively strongly absorbed. Comparison of the X-ray and radio maps allows to attribute some emission to a shell and some to the interior. With this information, a blastwave model can be used to derive approximate age and energy release. Both remnants have bright emitting regions inside the limb which might indicate the presence of high energy electrons accelerated by a pulsar. This relatively bright interior region is more prominent in G 327.1-1.1 than in Kes 27.
