Scientific paper

We propose to continue our Spitzer campaign on the 'Born Again' phenomenon. Our goals are to (i) follow the IR evolution of the dusty and molecular shell of Sakurai's Object, (ii) detect the effects of the star as it heats up, (iii) determine how the Aromatic Emission Features evolve from hydrogen-deficient objects to stars with normal H content, (iv) understand the origin of the mix of carbonaceous and silicate grains in the environment of O-rich binaries by observing XX Oph after it has emerged from a deep optical minimum.
