Description 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.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
