Scientific paper

IGR J21247+5058 is a new hard X-ray source in the Galactic plane, coincident with the core of the double radio source 4C 50.55. Our optical observations show that the counterpart of the radio core is a F9V star, displaying absorption lines with velocity shifts typical of an X-ray binary. New observations are in progress. The unprecedented property of this microquasar is the presence of a highly variable massive outflow. We propose XMM-Newton observations to confirm the proposed association between the X-ray source and the core of 4C 50.55, look for eventual X-ray emission from the radio lobes, obtain a detailed spectrum of the source to derive physical parameters (hydrogen column density, presence of iron or other eventual lines), and finally look for QPOs and other variability.
