Explicación paso a paso:Alhena is an evolving star that is exhausting the supply of hydrogen at its core and has entered the subgiant stage. The spectrum matches a stellar classification of A0 IV.[12] Compared to the Sun it has 2.8[6] times the mass and 3.3[7] times the radius. It is radiating around 123[7] times the luminosity of the Sun from its outer envelope at an effective temperature of 9,260 K.[8] This gives it a white hue typical of an A-class star.[13]
Alhena is a spectroscopic binary system with a period of 12.6 years (4,614.51 days) in a highly eccentric Keplerian orbit.[5]Alhena is an evolving star that is exhausting the supply of hydrogen at its core and has entered the subgiant stage.
