Scientific paper

Planetary nebulae (PNs) provide unique insights into a wide range of astrophysical phenomena. X-ray imaging of PNs by CXO has now broken open the study of very high temperature gas in these objects. To make further progress, we require detailed information concerning gas temperature and composition as a function of position within X-ray emitting PN "hot bubbles." Such information can be obtained only from observations combining high spectral and spatial resolution. We propose a 300 ks LETG/ACIS-S exposure of BD+303639, a particularly X-ray-bright PN. Such a deep, high spectral resolution observation of a PN has yet to be attempted. The proposed observation thus represents a potential breakthrough in our understanding of the origin and evolution of PNs.
