what % of solar energy is converted to solar neutrinos, assuming energy released in all forms per unit time , say 1 second as 100%?
Ref: http://csep10.phys.utk.edu/astr162/lect/energy/cno-pp.htmlIn the case of the Sun, detailed considerations suggest that it is producing about 98-99% of its energy from the PP chain and only about 1% from the CNO cycle. However, if the Sun were but 10-20% more massive, its energy production would be dominated by the CNO cycle.
Solar neutrinos are tiny, electrically neutral particles that are produced by nuclear reactions in the core of the sun. They are one of the byproducts of the fusion of hydrogen atoms into helium, which is the process that powers the sun's energy output.
Solar neutrinos carry energy in the form of kinetic energy. This means that they have a certain amount of energy based on their velocity and mass. Although they have very little mass, solar neutrinos travel at nearly the speed of light, allowing them to carry a significant amount of energy.
Solar neutrinos are important because they provide a direct measurement of the nuclear reactions happening in the core of the sun. As they travel through the sun, they interact with different types of particles, giving us information about the temperature, density, and composition of the sun's core. This helps scientists better understand the processes that produce the sun's energy.
Solar neutrinos are detected using large underground detectors, such as the Super-Kamiokande in Japan or the Sudbury Neutrino Observatory in Canada. These detectors are filled with a special liquid that can detect the faint flashes of light produced when a neutrino interacts with an atom in the liquid. By measuring the number and type of interactions, scientists can determine the properties of solar neutrinos.
Studying solar neutrinos allows scientists to test and improve our understanding of the fundamental processes that govern the behavior of matter and energy in the universe. It also provides insight into the composition and evolution of the sun, as well as the potential for using nuclear fusion as a clean and renewable energy source on Earth.
