Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy The positrons will almost instantly annihilate with electrons, releasing energy in the form of gamma rays. The neutrinos escape from the star carrying away some energy. One nucleus goes on to become carbon, nitrogen, and oxygen isotopes through a number of transformations in an endless loop. Overview of the CNO-I Cycl

About 99% of the energy output of the sun comes from the various p-p chains, with the other 1% coming from the CNO cycle. According to one model of the sun, 83.3 percent of the 4 He produced by the various p-p branches is produced via branch I while p-p II produces 16.68 percent and p-p III 0.02 percent the Sun is powered only by the PP process. Above about 3 solar masses, virtually all of the energy generated in a star comes from the CNO process. The mimimum mass of a star is about 0.075 solar masses. core of a gravitationally-collapsing gas sphere never rises high enough for hydrogen fusio The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. Depending on the kind of atom and the amount of energy, this electromagnetic radiation can take the form of heat, light, ultraviolet, or other electromagnetic waves The sun produces energy through nuclear fusion. The sun is a large ball of hydrogen and helium undergoing constant nuclear fusion, in which atoms of hydrogen combine to form helium and release a large quantity of energy. The enormous pressure in the sun keeps the fusion running for huge amounts of time. Because the sun is dense and massive, it.

The core is the only part of the Sun that produces an appreciable amount of heat through fusion. In fact, 99% of the energy produced by the Sun takes place within 24% of the Sun's radius. By 30%. Kinetic Energy - energy associated with motion; the kinetic energy of an object is equal to one-half the product of its mass and the square of its velocity. Light-Year - the distance light travels in one Earth year, equal to 9.46 x 10 12 km. Luminosity - the rate of radiation of electromagnetic energy into space by a star or other objec Energy is present whenever there are moving objects, sound, light, or heat. When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced Rather than releasing energy, the fusion of two iron nuclei requires an input of energy. Therefore, elements lighter than and including iron can be produced in a massive star, but no elements heavier than iron are produced. star, but no elements heavier than iron are produced. When the core can no longer produce energy to resist gravity, the. All of the energy we produce comes from basic chemical and physical processes. That's mostly been accomplished throughout history by burning carbon-based material like wood, coal and gas—or by harnessing power from the sun, wind, and water. Fission and fusion are two physical processes that produce massive amounts of energy from atoms

Some radiation, such as visible light, largely passes (is transmitted) through the atmosphere. These regions of the spectrum with wavelengths that can pass through the. Stars. A star is a sphere of gas held together by its own gravity. The closest star to Earth is our very own Sun, so we have an example nearby that astronomers can study in detail. The lessons we learn about the Sun can be applied to other stars. A star's life is a constant struggle against the force of gravity This resulted in the formation of light elements: hydrogen, deuterium, helium (two isotopes), lithium and trace amounts of beryllium. Nuclear fusion in stars converts hydrogen into helium in all stars. In stars less massive than the Sun, this is the only reaction that takes place. In stars more massive than the Sun (but less massive than about. The energy released during this process is what causes the sun (or any other star, for that matter) to burn. It takes nearly 10 million years to burn through the hydrogen and then things heat up and the helium begins fusing. Stellar nucleosynthesis continues to create heavier and heavier elements until you end up with iron absorption throughout the star (which only comes from metals). The smaller opacity allows the energy to escape more easily, and thus increases the luminosity via (3.1.4), i.e., L = − 16πacr2T3 3κρ dT dr (The effect is slightly less for higher mass stars, since the amount of energy generation is proportional to Z in CNO burning, but th
