Description It is commonly accepted that planetary nebulae (PNe) are formed by interactions between the current fast wind and a previous slow wind from the central star. The shock-heated fast wind in the central cavity should be a diffuse X-ray source. ROSAT observations of PNe have detected diffuse emission in two nebulae, NGC,6543 and Abell 30, but in both cases the X-rays appear to be associated with jets and outflows. To date, diffuse X-ray emission from shocked stellar winds in PNe has not been unambiguously detected. We request a 30 ks XMM EPIC pn observation of NGC,7009, which was detected but not resolved by the ROSAT PSPC. This observation and our complementary optical observations allow a comprehensive investigation of the wind-wind interaction model of PNe.

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.
