Description The hypergiant IRC+10420 is most probably a massive star evolving from the red supergiant phase to the Wolf-Rayet phase, crossing a particular location in the H-R diagram called the yellow void where stars are extremely rare and are dynamically unstable. This makes this object unique for the study of early-type star evolution, and the investigation of physical processes related to massive stars. Although several studies have been devoted to this enigmatic object in the infrared, it never benefited from a dedicated X-ray observation. We request a XMM observation of IRC+10420 aiming at characterizing for the first time its X-ray properties, and probe a part of the physics of this object that is not accessible at other wavelengths.

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.
