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.

What star in the life cycle of stars fuses hydrogen and helium?
A "red giant" star can fuse both hydrogen (in the star's outer shells) and helium (in the core).
What chemical is more abundant the older a star is?
As a star ages, it fuses hydrogen into helium in its core. Therefore, helium becomes more abundant in older stars compared to younger stars.
Is the sun made out of hydrogen and helium?
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.
Why is energy produced by the sun when hydrogen fuses into helium?
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.
What does the sun turn into helium?
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.
Can a red dwarf burn hydrogen?
A red dwarf fuses hydrogen into helium, just like any star, albeit at a very conservative rate.
Why do you have helium?
Helium exists because Hydrogen fuses into Helium in the core of hot stars.
The sun fuses hydrogen atoms into what?
Hydrogen atoms fuse into helium.
Does helium change into hydrogen in the center of the sun?
No. It is the other way around. Hydrogen nuclei fuses to form helium in the center of the sun.
The sun fuses hydrogen into what element?
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.
What does nuclear fusion give the sun?
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 what four nuclei bond together?
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.
What element is transformed in solar fusion?
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.
What fuses hydrogen to form helium?
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.
Is the oxygen sufficient for burning of hydrogen on the sun?
No. The hydrogen on the Sun does not burn; it fuses to make helium instead.
What is the product of a fusion reaction with the sun?
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.
How much energy is released when one gram of hydrogen fuses into helium?
5
