X-raying born-again planetary nebulae

Planetary nebulae have been a addition to the zoo of X-ray-emitting 
sources.  Here I present results on a the very particular class of 
born-again planetary nebulae, those whose central star has experienced 
a helium shell flash during the lifetime of the planetary nebula.  
The interaction of the fast stellar wind of the central star with 
hydrogen-poor material ejected during the born-again episode provides 
a unique case to study ablation, mass-loading winds, and charge-exchange 
processes.
