Star 'puffs' into red giant, shreds companion - aftermath spotted
Description
The Atacama Large Millimeter/submillimeter Array (ALMA) was used to observe star system HD 101584. A star in the system enlarged into a Red Giant and caused its companion star to shed it outer layers. The gas cloud that formed as a result was spotted by ALMA.
