| 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. Hillen et al. (2016) "Imaging the dust sublimation front of a circumbinary disk" http://arxiv.org/abs/1603.03023Sci-news: " VLTI Captures Best-Ever View of Old Star’s Dusty Disc" Maybe the data from IRAS 08544-4431 will help in determining whether second-generation planet formation can occur in such systems. | |
