Common envelope: Observational manifestations, Overview & Formation

In astronomy, a common envelope (CE) is gas that contains a binary-star system. The gas does not rotate at the same rate as the embedded binary system. A system with such a configuration is said to be in a common-envelope phase or undergoing common-envelope evolution.
