| Description | While >200 extra-solar planets orbiting main-sequence stars have been discovered, the destiny of planetary systems through the late stages of the evolution of their host stars is very uncertain, and no planet has been found around a white dwarf. We have identified a metal-rich gas disk around the relatively young white dwarf SDSS 1228+1040. A dynamical model of the double-peaked emission lines constrains the outer disk radius to just 1.2Rs. The likely origin of the disk is a tidally disrupted asteroid, which has been destabilised from its initial orbit at a distance of more than 1000 solar radii by the interaction with a rather massive planetesimal or planet. We propose a VLT and XMM study of the nature of the planetary debris disk around SDSS 1228+1040 and its interaction with the WD |

| 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. |
