Web7 de out. de 2024 · Create heavier elements such as iron. Now iron can't certainly not sustain a star. As such the iron destroys the star, thus marking the end of its life cycle. Small amounts of iron probably exist in stars, (from the universes point of view.) But it's not enough to actually effect the star it's in. WebIn 1938 German-born physicist Hans Bethe proposed the first satisfactory theory of stellar energy generation based on the fusion of protons to form helium and heavier elements. He showed that once elements as heavy as carbon had been formed, a cycle of nuclear reactions could produce even heavier elements.
WebFormation of Heavier Elements in the Evolution of Universe The nucleosynthesis epoch All elements in the universe – natural or synthetic – form through nucleosynthesis. Nucleosynthesis means (nucleo, meaning “nucleus”; synthesis, meaning “putting together”) is defined as the formation of elements by combining the simple nuclei or atomic …
