Abstract Planetary nebulae (PNe) consist of stellar material ejected by stars lessmassive than than 8--10 solar masses during the asymptotic giant branch (AGB)phase. There is strong evidence that fast collimated outflows or jets that occurtoward the end of the AGB phase are responsible for producing the bipolar ormulti-polar shapes of PNe. However, the origin of collimated outflows in PNe isnot clear. Stellar magnetic field has been invoked as the launching mechanismfor collimated outflows in PNe, but supporting evidence is lacking.The young PNK 3-35 is the only known PN whose bipolar outflows appear to be collimated by amagnetized torus. We request XMM-Newton observations of K 3-35 to search for theX-ray emission associated with the stellar corona powered by the magnetic field.

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.
