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

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
