Spectra of Betelgeuse and Rigel - Harvard University.
Orion, one of the most famous winter constellations, shines bright with the stars Rigel and Betelgeuse taking center stage in Orion's belt.Betelgeuse, second brightest star in the constellation Orion, marking the eastern shoulder of the hunter. It has a variable apparent magnitude of about 0.6 and is one of the most luminous stars in the night sky. A red supergiant star roughly 950 times as large as the Sun, Betelgeuse is one of the largest stars known.Life Cycle of Betelgeuse Middle Age Afterlife Old Age When Betelgeuse ran out of helium to burn, its core began to collapse and heat up. That made the outer layers cool and expand, thus growing larger and larger until eventually becoming a red supergiant. After a red supergiant.
About 1000 times larger and about 10 times more massive. Neither values are particularly well defined, however, and it pulsates so its radius is constantly changing. It’s also a supergiant star in the last stages of it’s life so it’s expanded well.Spectra of Betelgeuse and Rigel. The spectrum of a star can give us a lot of information about the star, including information about its composition and its temperature. In this lab, you will take the spectrum of two different stars and identify their spectral type. Stars are divided into groups (O, B, A, F, G, K, M) from hottest to coolest.
Betelgeuse is well-known because of its bright size and easy-to-spot location in the constellation Orion. It is of astronomical interest because it will likely go supernova in less than a million.
