WebNov 1, 2016 · $\begingroup$ Controlled nuclear fusion employs temperatures much greater than those at the center of the Sun, but at a vastly pressure compared to the center of the Sun. Controlled fusion also bypasses the initial proton-proton fusion step, which is the bottleneck in fusion in a one solar mass star. This bottleneck is why even though it is 4.6 … WebFigure 25.9. 2: (left) The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second. (right) The proton-proton chain dominates in stars the size of the Sun or smaller. Example 25.9. 1.

WebNuclear fusion powers a star for most of its existence. Initially the energy is generated by the fusion of hydrogen atoms at the core of the main-sequence star. Later, as the preponderance of atoms at the core becomes helium, stars like the Sun begin to fuse hydrogen along a spherical shell surrounding the core. WebIn a proton-proton chain, four hydrogen nuclei are combined to form one helium nucleus; 0.7 percent of the original mass is lost mainly by conversion into heat energy, but some …

WebJan 21, 2024 · Proton-proton chain - This sequence is the predominant fusion reaction scheme used by stars such as the sun. Two pairs of protons form to make two deuterium atoms.
