We propose to secure a 50 ksec exposure with XMM-Newton of the Planetary NebulaAbell30. This PN has a hydrogen-deficient central star of WC-PG1159 transitiontype and fits into the ..born-again. scenario. We expect to detect at least1000 X-ray counts from the ..hot bubble., that will allow us to address thephysics of the ..hot bubbles. inside Planetary Nebulae, and in particular therole of heat conduction for explaining their surprisingly low electrontemperature. The analysis of EPIC spectra will also allow to investigateevolutionary origin of hydrogen-deficient post-AGB stars, in particular to checkthe validity of the ..born-again scenario..

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.
