| Abstract | We propose a follow-up XMM study of RXJ0806.3+1527, a double degenerate binarysystem with the shortest orbital period known (321 s). Chandra ACIS-S and XMMobservations carried out in November 2001 and 2002 (simultaneously with VLTobservations) strengthen the above interpretation and allow us to characteriseits soft X-ray spectrum (a low-absorbed blackbody component with kT=65eV).However, in both the Chandra and XMM observations we found evidences forspectral features which we identified as Fe XVII and He- and H-like O absorptionedges. The requested XMM observation is mainly aimed at characterising theseabsorption features and searching for additional ones testifying to the presenceof heavy chemical elements. |

| 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. |
