Web14 aug. 2024 · The prime energy producer in the Sun is the fusion of hydrogen to form helium, which occurs at a solar-core temperature of 14 million kelvin. The net result is the fusion of four protons into one alpha particle, with the release of two positrons, two neutrinos (which changes two of the protons into neutrons), and energy (Figure 20.9.2 ). WebThese lines came to be known as ‘spectral lines’ and were cataloged by heating common elements until they produced light and measuring the ... as well as the atmosphere of stars and planets (that absorb light passing through their atmospheres).

How is energy produced in stars? - Answers
Web20 feb. 2024 · A star produces energy by creating helium from hydrogen in its core (option D).. How does a star produce energy? A star is a luminous celestial body, made up of … Webis related to the internal energy by P = (γ − 1) u . Therefore Z R 0 P dVr = (γ − 1) Z R 0 u dV = (γ −1) U , where U is the total internal (thermal) energy of the star. Thus we arrive at The Virial Theorem: Ω = − 3 (γ − 1) U Consider the case relevant to most stars, where the material behaves as an ideal, monatomic gas. WebIn the cores of lower-mass main-sequence stars such as the Sun, the dominant energy production process is the protonproton chain reaction. This creates a He-4 nucleus … income limitations for hsa
