NotesPart of the Kids formation within Auriga, the nature of the Almaaz system is still under investigation. It has an unusual pattern of variability, which seems to suggest that the system consists of a primary F-type bright yellow star, probably a supergiant, orbited by a less massive star which is surrounded by a disc of obscuring dust.
