Scientific paper

It is commonly accepted that fast stellar winds and fast collimated outflows are responsible for the shaping of planetary nebulae (PNe). Both fast stellar winds and collimated outflows can produce shock-heated gas that emits diffuse X-rays; thus, X-ray observations of PNe can be used to gain insight into the formation and shaping of PNe. Few PNe, however, show detectable diffuse X-ray emission and in only two cases this can be attributed to fast collimated outflows. Our XMM-Newton observations of the Eskimo Nebula reveal diffuse X-ray emission that may originate from both its fast stellar wind and from its bipolar outflows. We request Chandra ACIS observations to resolve the X-ray emission from the Eskimo Nebula and to determine its origin.
