DISCOVERY OF X-RAYS FROM THE COMPOSITE SUPERNOVA REMNANT G0.9+0.1 WITH THE BEPPOSAX SATELLITE

Using the BeppoSAX satellite we have obtained the first secure X-ray d etection of the supernova remnant G0.9+0.1. The 1-10 keV spectrum can be described with an absorbed power law with alpha similar to 3 and N- H similar to 3 X 10(23) cm(-2). The high column density supports a dis tance similar to that of the Galactic Center. The X-ray emission, with a luminosity L-x similar to 10(35) d(10)(2) erg s(-1), coincides with the central radio core, confirming the composite nature of this remna nt. Though a search for periodic pulsations gave a negative result, th e observed X-rays are probably related to the presence of a young radi o pulsar at the center of G0.9+0.1.
