What is 49 Ceti

49 Ceti is a white A-type star burning at 194 light-years inside the celestial whale, and it holds something extraordinary: around it persists a disk of gas and dust, primordial leftovers of planetary formation that radio telescopes have detected in carbon monoxide. It is one of the most studied examples of a debris disk with residual gas, a rarity for a star already entering its maturity.
