What type of stellar system is the highly luminous Eta Carinae star?
Answer
A binary system
The central feature of the Carina Nebula is the Eta Carinae star system, which is definitively described as a binary system. This system is dominated by a star that exhibits incredible luminosity, radiating energy equivalent to millions of times the output of our Sun. Because it is a binary system, the interaction between the two massive components contributes significantly to the nebula's energetic environment. Observing this system is complex, often requiring infrared observations because intervening dust frequently shrouds the true nature and luminosity of the primary star from direct visible light observation.
