How is oxygen formed in stars

Web3 okt. 2024 · If a star cluster contains only very small amounts of elements such as oxygen, iron, and gold when compared to our sun, the stars were likely very early stars, and hence very old. Yet if there is a large abundance of all elements compared to our sun, then they must be formed from the remnants of previous explosions, making them part of a much … WebAfter the hydrogen in the star's core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and nickel requires an input of energy.

Web25 jan. 2024 · Stars are in the business of producing energy to radiate into space, which fusion accomplishes nicely. But fusing nuclei heavier than iron consumes energy, rather than releasing it. Populating the rest of the periodic table — the dozens of elements with atomic numbers higher than iron — requires a different strategy. Web3 nov. 2024 · The element oxygen is formed from carbon fusion; neon from oxygen fusion; magnesium from neon fusion: silicon from magnesium fusion; and iron from silicon fusion. The star becomes a multiple-shell red giant. Learn about it! The fusion of elements continues until iron is formed by silicon fusion.
