In dwarf stars, the fusion of hydrogen into helium primarily occurs through the proton-proton chain reaction. In this process, four hydrogen nuclei (protons) are ultimately converted into one helium-4 nucleus, releasing energy in the form of gamma rays, positrons, and neutrinos. This energy production is what powers dwarf stars, allowing them to maintain stability against gravitational collapse. As hydrogen is consumed, the star evolves, leading to changes in its structure and lifecycle.
A "red giant" star can fuse both hydrogen (in the star's outer shells) and helium (in the core).
As a star ages, it fuses hydrogen into helium in its core. Therefore, helium becomes more abundant in older stars compared to younger stars.
It definitely runs on hydrogen, and its made of helium, as well. --- Yes, it is mainly made of hydrogen which it uses as a fuel. It fuses hydrogen nuclei together to form helium, producing huge amounts of energy through this nuclear fusion reaction. Helium is produced by this reaction. The most important fusion reaction is stars the size of our Sun, is the so called 'Proton - proton' reaction, which in summary, combines 4 nuclei of Hydrogen to produce one nucleus of Helium, plus two nuclei of Hydrogen, and positrons and gamma rays. Gamma rays get transformed inside the sun into less harmful electromagnetic radiations. There are other fusion reaction inside stars, which combine lighter atom nuclei into heavier nuclei, going up to producing carbon C and iron Fe nuclei.
Energy is produced in the sun when hydrogen fuses into helium through a process called nuclear fusion. This process releases a huge amount of energy in the form of light and heat due to the conversion of mass into energy according to Einstein's famous equation, E=mc^2.
If you are asking "how helium formed the sun?" then for your information, sun and all the stars are formed mostly from Hydrogen. And if you are asking "How helium is formed in the sun?", the answer is that the Hydrogen in the sun fuses in itself(that's where from the sun get's its energy and luminosity) producing variety of elements like helium, carbon oxygen,iron etc.
A red dwarf fuses hydrogen into helium, just like any star, albeit at a very conservative rate.
Helium exists because Hydrogen fuses into Helium in the core of hot stars.
Hydrogen atoms fuse into helium.
No. It is the other way around. Hydrogen nuclei fuses to form helium in the center of the sun.
The sun fuses hydrogen into helium through a process called nuclear fusion. This process releases a tremendous amount of energy in the form of light and heat.
The sun fuses hydrogen into helium. The mass of the resulting helium is not the same as the original hydrogen. The difference is energy.
During the solar nuclear reaction, in the proton-proton chain, four hydrogen nuclei (protons) bond together to form a helium nucleus. Two protons combine to form a deuterium nucleus, which then fuses with another proton to form helium-3. Two of the helium-3 nuclei then fuse to form helium-4.
Our sun mostly transforms hydrogen nuclei into helium by fusion, but it also fuses helium with helium, lithium with hydrogen, and beryllium with hydrogen, to make elements as heavy as boron.
Nuclear fusion is the process that fuses hydrogen atoms together to form helium. This process occurs in the core of stars, including our sun, where high temperatures and pressures allow hydrogen nuclei to overcome their electrostatic repulsion and combine to form helium nuclei.
No. The hydrogen on the Sun does not burn; it fuses to make helium instead.

In the sun the product of the nuclear fusion is light energy and heat energy. It also created helium from the isotopes deuterium and tritium.
