Abstract | GT-Iota Orion is a massive O-B binary in a highly eccentric orbit. Instabilitesin the individual winds and the collisions between the two winds are expectedto produce x-ray emitting shocked regions. With the high-resolution of the RGSwe will study the composition and structure of the two stellar winds as well asthe dynamics and emission mechanism of the collision regions. We willmap the complete field with the EPIC cameras to investigate X-ray emissionfrom young and forming stars. |

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. |
