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

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.
