Scientific paper

Planetary nebulae (PNe) consist of stellar material ejected by stars less massive than than 8--10 solar masses during the asymptotic giant branch (AGB) phase. There is strong evidence that fast collimated outflows or jets that occur toward the end of the AGB phase are responsible for producing the bipolar or multi-polar shapes of PNe. However, the origin of collimated outflows in PNe is not clear. Stellar magnetic field has been invoked as the launching mechanism for collimated outflows in PNe, but supporting evidence is lacking.The young PN K 3-35 is the only known PN whose bipolar outflows appear to be collimated by a magnetized torus. We request XMM-Newton observations of K 3-35 to search for the X-ray emission associated with the stellar corona powered by the magnetic field.
