What else can I help you with?
Where is beryllium formed in stars?
Helium and metals (which basically means any element heavier than helium) are formed in the star's core.
How is helium formed in the universe?
Helium is formed in the universe through nuclear fusion processes that occur in stars. During the fusion of hydrogen atoms in the core of a star, helium is produced as a byproduct. This process releases a large amount of energy and is responsible for the creation of helium in the universe.
Why do you have helium?
Helium exists because Hydrogen fuses into Helium in the core of hot stars.
How are elements formed?
Hydrogen and helium were formed shortly after the creation of the universe (when the protons and alpha particles combined with electrons). Everything else was formed within the core of stars (by fusion reactions).
What type of star burns helium?
All red giant stars will start helium fusion when their core is compressed.
What does helium have to do with a star?
Helium is formed in the core of the star (like the sun) by the nuclear fusion of hydrogen isotopes.
What process powers most stars including our Sun?
The energy radiated by the Sun comes from nuclear fusiondeep in its core. Main sequence stars like the Sun fuse hydrogen into helium until they exhaust their supply, over billions of years. Eventually they may swell into red giant stars that fuse helium into carbon.
Is the sun made out of core?
No, it is formed by fusion of hydrogen and helium molecules.
What chemical is more abundant the older a star is?
As a star ages, it fuses hydrogen into helium in its core. Therefore, helium becomes more abundant in older stars compared to younger stars.
How are super-Giants are formed?
Supergiants develop when massive main-sequence stars run out of hydrogen in their cores. They then start to expand, just like lower-mass stars, but unlike lower-mass stars, they begin to fuse helium in the core almost immediately.
What are all of the elements found in the core of a star?
For stars on the main sequence, Hydrogen and helium.
Why does the amount of hydrogen in a star decrease?
The amount of hydrogen in a star decreases over time because hydrogen fuses into helium through nuclear reactions in the star's core, releasing energy in the process. As the star continues burning hydrogen, it eventually exhausts its hydrogen fuel supply, leading to changes in its structure and behavior.
