Description We propose joint observations with Chandra and XMM-Newton of the super Chandrasekhar mass white dwarf merger product Cas J005311. A first pilot XMM-Newton observation revealed an astonishingly high X-ray luminosity of Cas J005311 and its remarkable nebula which is strongly enriched in Neand Mg. The proposed ACIS-I observations will map the nebula and probe chemical gradients across it, as necessary to unravel the evolutionary history of the merger. We will search for X-ray pulsations to test magnetic fields and rotation of Cas J005311. Jointly, Chandra and XMM-Newton will reveal the physical mechanisms powering the X-rays from the central star and the nebula.

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.
