[EX Q]: Question: What is the official IAU name for the main star that is ioninizing  the surrounding material? Passage:Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.

It is depicted as a fire-breathing monster with the heads of a lion and a goat next to each other, the front legs of a lion, the wings of a dragon, the hindquarters of a goat, and a snake-headed tail, while also possessing the power of speech. Its history of being the offspring of Echidna and being slain by Bellerophon is still mentioned. At some point, the Chimera was restored to life by Hera to guard the caverns underneath New Olympus. It was accompanied in this job by a Cyclops and some Skeleton Warriors. The Chimera encountered the Agents of Atlas. When it didn't see that they were Olympians, Chimera breathed fire at them, sparking a fight between the heroes and the minions of Hera. Gorilla-Man forced the chimera to set its second head ablaze, causing it to flail around until it was knocked unconscious.
