Description We propose to secure a 50 ksec exposure with XMM-Newton of the Planetary Nebula Abell30. This PN has a hydrogen-deficient central star of WC-PG1159 transition type and fits into the ..born-again. scenario. We expect to detect at least 1000 X-ray counts from the ..hot bubble., that will allow us to address the physics of the ..hot bubbles. inside Planetary Nebulae, and in particular the role of heat conduction for explaining their surprisingly low electron temperature. The analysis of EPIC spectra will also allow to investigate evolutionary origin of hydrogen-deficient post-AGB stars, in particular to check the validity of the ..born-again scenario..

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.
