| Abstract | The effects of heat conduction, though promising in application to H-rich PNe,are uncertain in the case of H-poor PNe. Here, we propose observations of twoH-poor, WC-type, PNe, NGC 6369 and NGC 1501. These two PNe, which harborcentral stars with high effective temperatures, will provide heretofore missingconstraints on evolutionary models of PNe and thereby motivate the developmentof H-poor heat conduction studies. The large (20-30 radii), well defined shellsof these nebulae, combined with their moderate extinction and relativeproximity, make them optimal candidates for X-ray detection and study inmoderate (40 and 25 ks) exposure times with XMM-Newton. |

| 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. |
