2017年4月24日 · Nuclear fusion is the lifeblood of stars, and an important process in understanding how the universe works. The process is what powers our own Sun, and therefore is the root source of all the energy on Earth.

In astrophysics, stellar nucleosynthesis is the creation of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred since the original creation of hydrogen , helium and lithium during the Big Bang .

2025年2月22日 · The proton-proton nuclear fusion cycle in a star containing only hydrogen begins with the reaction H + H → D + β + + ν; Q = 1.44 MeV, where the Q-value assumes annihilation of the positron by an electron.

Nuclear fusion is the process that powers active or main-sequence stars and other high-magnitude stars, where large amounts of energy are released. A nuclear fusion process that produces atomic nuclei lighter than iron-56 or nickel-62 will generally release energy.

2024年3月21日 · Nuclear fusion is the process that powers stars and allows them to shine brightly. In the early stages of a star’s life, hydrogen fusion in the core produces the energy that counteracts the force of gravity, preventing the star from collapsing.

2022年9月21日 · It is nuclear fusion that supplies the stars — including the sun — with their energy, allowing them to generate light. The vast majority of energy that Earth receives comes from the sun,...

2024年9月1日 · Stellar nucleosynthesis is the process through which elements are created within stars, by combining the protons and neutrons together from the nuclei of lighter elements. All of the atoms in the universe began as hydrogen. Fusion inside stars transforms hydrogen into helium, heat, and radiation.
