The dusty ring around the aging double star IRAS 08544-4431

The Very Large Telescope Interferometer at ESO’s Paranal Observatory in Chile has obtained the sharpest view ever of the dusty disc around the close pair of aging stars IRAS 08544-4431. For the first time such discs can be compared to the discs around young stars — and they look surprisingly similar. It is even possible that a disc appearing at the end of a star’s life might also create a second generation of planets.

This view shows the VLTI reconstructed image, with the brighter central star removed. A fainter glow from the secondary star is visible, which came as a surprise to the observers.
