Scientific paper

The biggest stumbling blocks to progress in our understanding of the death of intermediate-mass stars and the accompanying formation of planetary nebulae (PNs), are the complex stellar-wind episodes and the interactions between them which occur during the post-AGB phase. We propose ACIS-S observations of 5 young PNs with very fast outflows for which HST emission-line images are available, in order to directly probe the very hot (10(7-8) K) shocked gas resulting from the most recent wind-wind interactions in these objects, as well as compact X-ray emission from the (possibly) magnetised central stars. A comparative analysis of the CXO and HST data on these PNs, supplemented by detailed modelling, will be invaluable in solving the mystery of how PNs are formed and shaped.
