Image of a disc around a post-AGB system

Images of a circumbinary disc around the binary star IRAS 08544-4431 (V390 Velorum). The system is binary (the primary being a post-AGB star) and there appears to be an accretion disc around the secondary.

Maybe the data from IRAS 08544-4431 will help in determining whether second-generation planet formation can occur in such systems.
