How Aldebaran was born? Aldebaran was born or made when atoms of light are squeezed under tons of pressure for a nuclei to undergo a fusion. Then it collapses and continues to spin and the temperature rises. Then cloud of gas soon separates into many tiny pieces of cloud gas which is spinning faster then the outer layer. The cloud begins to move faster and faster to conserve a angular momentum.
When the center of the could gas temperature rises to 2,000 Degrees Kelvin then hydrogen gas molecules break apart and turn into hydrogen atoms. Then when the temperature reaches about 10,000 Degrees Kelvin its starts to look like at star when a fusion reactions begins. Then when it collapse to the size of the sun it becomes a protostar When the core has great enough pressure and temperature and can sustain a nuclear fusion, the outward pressure acts against force. The dust is still surrounding the star, the star is heating up and glowing in the infrared part of the spectrum. Then the radiation pressure from the stars blows away the envelope and then the star starts its evolution. |
Nuclear Fusion
A Nuclear Fusion is when two hydrogens atoms are combined into a deuterium atom. Deuterium can be combined with hydrogen atoms and become tritium. When deuterium and tritium are combined they let out energy. The star is making more energy then it is releasing in and it soon will explode. The conditions for a nuclear fusion temperature requires to be about 100 million Kelvin an they have to have high pressures.
