Fusion reactions can occur inside stars for two reasons...
- The temperature is extremely high, resulting in full ionization of the electrons from the hydrogen atoms. This removes one of the barriers from the fusion process that would interfere due to the electromagnetic force.
- The pressure is also extremely high, high enough to overcome the repulsion of the protons in the hydrogen atoms also due to the electromagnetic force, allowing the hydrogen atoms to fuse into helium atoms. The weak interaction then causes two of the protons to change into neutrons, completing the change into helium.
Both of these conditions are initiated by gravity.
What else can I help you with?
When nuclear fusion occurs what form of radiation is released from the star?
Positrons and neutrinos are released by nuclear fusion.
What is the nuclear fusion order in a star?
In a star, nuclear fusion occurs in multiple stages. The main sequence stars, like our sun, primarily fuse hydrogen into helium in their cores through the proton-proton chain reaction. As the star evolves, it can go on to fuse heavier elements like carbon, oxygen, and eventually iron through various nuclear reactions.
Which nuclear fusion cycle is the next one to begin after helium fusion ends in a massive star?
The next nuclear fusion cycle after helium fusion in a massive star is carbon fusion. This process involves fusing helium nuclei to form carbon. Carbon fusion typically occurs in the core of a massive star after helium fusion is completed.
Do nuclear fusion occurs as stars cool down?
No, nuclear fusion does not occur as stars cool down; rather, it occurs in the core of stars when they are hot and under immense pressure. As a star evolves and exhausts its nuclear fuel, it may cool down and undergo changes, but fusion primarily happens during the star's life cycle when temperatures are extremely high. Eventually, a star may end its life in a cooler state, but fusion processes cease long before that, depending on the star's mass and composition.
What is the nuclear fusion order for a star?
The nuclear fusion order for a star like our Sun involves the conversion of hydrogen into helium. This fusion process occurs in multiple stages, beginning with the fusion of hydrogen isotopes (protons) into deuterium, and then further reactions combine deuterium to form helium-3 and, ultimately, helium-4.

What is the name of the reaction tat occurs in the core of a star that makes the star hotter and luminescent?
Nuclear fusion, when hydrogen under extreme heat and pressure will fuse into helium and release a tiny bit of energy.
Which nuclear fusion cycle is the next one to begin after helium fusion ends in a massive star?
The next nuclear fusion cycle after helium fusion in a massive star is carbon fusion. This process involves fusing helium nuclei to form carbon. Carbon fusion typically occurs in the core of a massive star after helium fusion is completed.
What is the name of the nection that occurs in the core of a star that makes it hot and luminescent?
Stars are powered by nuclear fusion, in which atoms of hydrogen are fused into atoms of helium, releasing a little energy with each reaction.
Do nuclear fusion occurs as stars cool down?
No, nuclear fusion does not occur as stars cool down; rather, it occurs in the core of stars when they are hot and under immense pressure. As a star evolves and exhausts its nuclear fuel, it may cool down and undergo changes, but fusion primarily happens during the star's life cycle when temperatures are extremely high. Eventually, a star may end its life in a cooler state, but fusion processes cease long before that, depending on the star's mass and composition.
What nuclear reaction occurs in stars?
In stars, the primary nuclear reaction is nuclear fusion, where lighter atomic nuclei combine to form heavier nuclei, releasing vast amounts of energy. The most common fusion process in stars like the Sun is the conversion of hydrogen into helium through a series of reactions known as the proton-proton chain. This reaction releases energy in the form of light and heat, which powers the star and contributes to the processes that sustain life on Earth. In more massive stars, other fusion processes can occur, including the fusion of helium into heavier elements.

This fusion process occurs in multiple stages, beginning with the fusion of hydrogen isotopes (protons) into deuterium, and then further reactions combine deuterium to form helium-3 and, ultimately, helium-4.
