Title The Earliest Production of Hot Gas in Young Planetary Nebulae

Author Dr Martin Guerrero
Description Planetary nebulae (PNe) consist of stellar material ejected by stars with masses <10 solar masses. Both fast stellar winds and collimated outflows contribute to the shaping of PN shells and fill the shell interiors with shock-heated gas at temperatures higher than 10E6 K. XMM and Chandra observations have produced the first unambiguous detections of diffuse X- ray emission from PNe, but the observed X-ray luminosities of PNe are generally much lower than theoretical expectations. Observations of a few young PNe hint at a short-lived phase of bright X- ray emission in early evolutionary stages. We request XMM observations of 4 very young PNe to further investigate the earliest history and physical conditions of hot gas produced by fast winds and collimated outflows in 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.
