This story refers to the star Betelgeuse. It talks about the life cycle of that star and gives description about it.
My name is Betelgeuse and I was born from a nebula.
I ran out of helium to burn and I'm starting to heat up.
I'm now a red supergiant because my outer layers cooled.
I am currently 950 times as big than the sun.
After 100,000 years, I died because I ran out of fuel and exploded making myself a supernova.
Betelgeuse became a massive star due to running out of hydrogen and started expanding when he was born.
When Betelgeuse ran out of helium he started to heat up. Afterwards, his layers cooled down and became a red supergiant. He is supergiant because he is 950 times as large than the Sun.
Extra Information: -Betelgeuse's mass is 7.7 M. -It's apparent magnitude varies between 0.0 and 1.3. -Does not belong in the main sequence group like most stars are.
When Betelgeuse died, it was because he ran out of fuel to burn and exploded making himself a supernova.
Fun Important Facts To Know: 1. The initial mass of a star affects it's evolution by growing by the formation of gas and dust from a molecular cloud. 2. Scientists can find the temperature of a star by finding the dominant wavelength of a star's light. 3. Blackbody radiators is an ideal radiator and absorber of energy for all electromagnetic wavelengths. 4. hot stars appear to be blue because blue light photons have a shorter wavelength and more energy than red stars.
Betelgeuse will always be remembered for his luminosity which was the 2nd brightest star in Orion, his radius that was 820.9 km, his surface temperature at 3,500 K, and his spectral type which is M2lab.
In Betelgeuse's afterlife, you might have thought that he became a white dwarf but he didn't, he became one of two choices. A black hole or a neutron star.
