| Abstract | Sigma Ori E-type objects are a class of massive, rapidly rotating stars thatexhibit magnetically confined disks supplied by mass loss from their centralstar. Discrepancies between the observed disk geometry, the detailed locationand amount of shocked gas in these disks, and the magnetic field morphology ofthese systems with predictions from rigid-field hydrodynamical models suggestsour basic understanding of sigma Ori E-type objects is incomplete. We propose touse XMM-Newton to diagnose the shocked gas component in three sigma Ori E-typeobjects and compare their X-ray properties to other sigma Ori E systems tobetter understand the class as a whole. |

| 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. |
