WebIf the mass of a nubile star is in the range of 0.4 - 8 M, then further fusion processes can occur. In this case, the helium will accumulate within the core. Once the initial hydrogen fusion stops, the star will re-equilibrate its internal hydrostatic pressures by expanding its outer layers to become what is called a giant.

Web7 de mai. de 2015 · That is, the thermal energy due to the high temperature breaks silicon nuclei into separate helium nuclei. These helium nuclei then combine with elements such as chlorine, argon, potassium, and calcium to make elements from titanium through iron. Large stars also produce elements heavier than iron via neutron capture. Web25 de out. de 2024 · Most elements lighter than iron are forged in the cores of stars, but scientists have puzzled over what could give rise to gold, platinum, and the rest of the universe’s heavy elements. An MIT study finds that of two long-suspected sources of heavy metals, one of them — a merger between two neutron stars — is more of a goldmine … WebThe resulting proton-neutron pair can form a stable deuterium nucleus that is then the starting point for the production of helium.
