Stars in the universe are planned through a cognitive operation called nucleosynthesis, which fuses lighter atoms to create untried heavier atomic nuclei.
How does stellar nucleosynthesis produce heavier elements?
Stellar nucleosynthesis continues to create heavier and heavier elements until you end up with iron. Creating the Heavier Elements The burning of helium to produce heavier elements then continues for about 1 million years.
How are the elements involved in nucleosynthesis?
Precisely which elements are involved in nucleosynthesis depends on the age and mass of the star. The most prevalent reaction in smaller stars like our Sun is the fusion of hydrogen into helium by the proton-proton chain; in more massive stars this fusion occurs via the carbon cycle.
Where does nucleosynthesis take place in a star?
Nucleosynthesis is the process by which heavier chemical elements are synthesized in the interiors of stars from hydrogen nuclei and other previously synthesized elements.
When did stellar nucleosynthesis occur in the Big Bang?
Stellar nucleosynthesis has occurred continuously since the original creation of hydrogen, helium and lithium during the Big Bang. It is a highly predictive theory that today yields excellent agreement between calculations based upon it and the observed abundances of the elements.
