- All stars live by fusing hydrogen into helium. In the first step of the process, two hydrogen atoms fuse to form deuterium. In the next step, another hydrogen atom fuses with the deuterium, creating a rare isotope of helium that has two protons and one neutron in its nucleus. In the third step, two of the rare helium atoms fuse to create a single normal helium atom and two hydrogen atoms. The fusion pathway described above requires six hydrogen atoms to create one helium atom—however, there are two hydrogen atoms left over at the end of the process. The net result is that it takes four hydrogen atoms to make one helium atom.

- To release energy, carbon-12 and heavier elements must be created. Carbon-12 is created when helium-4 combines with beryllium-8. In this interaction, carbon-12 nucleus is left in an energetic state from which it decays, releasing a gamma-ray. The conversion of beryllium-8 into carbon-12 releases 7.37 MeV.. C 12 + γ. The process of converting three helium-4 nuclei into a single carbon-12 nucleus releases a total of 7.27 MeV, all of which remains trapped within the star. This fusion chain can be treated as a single process; it is then called the triple-alpha process (an alpha particle is a helium-4 nucleus).

What is the difference between nuclear fusion and nuclear fission? A huge amount of mass is above you, squeezing down on you from all sides. This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion. In the process some of the mass of the hydrogen atoms is converted into energy in the form of light. The same process occurs in thermonuclear (fusion) bombs. In the Sun the process occurs in a controled manner. In a bomb it happens all at once in a big chain-reaction explosion.

Stage 1: Glucose Breakdown The second step of glycolysis involves the conversion of glucose-6-phosphate to fructose-6-phosphate (F6P). This reaction occurs with the help of the enzyme phosphoglucose isomerase (PI). As the name of the enzyme suggests, this reaction involves an isomerization reaction.

astro test 2 Without fusion, there would be no life on Earth. What we see as light and feel as warmth is the result of a fusion reaction in the core or our Sun: hydrogen nuclei collide, fuse into heavier helium atoms and release tremendous amounts of energy in the process.

Fusion Light nuclei join to form a heavier nucleus. Energy is released in the process. Fusion powers the stars and high yield thermonuclear weapons. Stars begin as a cloud of mostly hydrogen with about 25% helium and heavier elements in smaller quantities. The sun, 107 K core, hydrogen fuses to form helium through a process known as the proton-proton chain (often shortened to the p-p chain). More on stellar fusion in another section of this book.

The Hydrogen Fusion Process The Hydrogen Fusion Process. In the basic Hydrogen fusion cycle, four Hydrogen nuclei (protons) come together to make a Helium nucleus. This is the simple version of the story. There are actually electrons, neutrinos and photons involved that make the fusion of Hydrogen into Helium possible. The important thing to remember is that this fusion cycle releases energy in the core of the star. It is this fusion cycle that generates energy in our Sun.

Hydrogen By far the most important process for making hydrogen is by steam reforming. The key parts of the process are the conversion of a carbon-containing material to a mixture of carbon monoxide and hydrogen followed by the conversion of carbon monoxide to carbon dioxide.

- WHAT IS FUSION? Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium.

Fusion - Energy Production in Stars An even rarer form of fusion in Sun-like stars is the PPIII chain, which fuses elements through lithium, beryllium, and boron, but destroys them in the end, effectively using them as catalysts: This process starts with an atom of beryllium-7 (from the first step of the PPII chain) and a proton (known as proton capture), and it fuses them into boron-8.

RED GIANTS The star now has THREE main layers: ( 1 1) Helium core (inner layer): Releases energy as it shrinks in radius. ( 2 2) Fusion shell: Releases energy as it fuses hydrogen into helium. ( 3 3) Hydrogen envelope (outer layer): Absorbs energy, and swells greatly in size.

Nuclear Fusion Temperatures required for fusion reactions exist in stars where fusion reactions are the principle components of energy release. In the Sun, approximately 90 percent of solar energy is a result of proton–proton interactions in several steps to form helium of mass number 4.

Stages of Mitosis The fourth and last stage of mitosis. During this stage the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.

AST1002 Chapter 13 In the first, the primary production of energy is from hydrogen burning in a shell around the core. In the process of helium shell fusion in a low-mass star near the end of its life, the star moves upward and to the right on the asymptotic giant branch of the Hertzsprung-Russell diagram.

Contents: Nuclear Fission and Fusion Nuclear fusion is the reaction in which two or more nuclei combine, forming a new element with a higher atomic number (more protons in the nucleus). The energy released in fusion is related to E = mc 2 (Einstein’s famous energy-mass equation). On Earth, the most likely fusion reaction is Deuterium–Tritium reaction.

- Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy. The easiest fusion reaction to make happen is combining deuterium (or heavy hydrogen) with tritium (or heavy-heavy hydrogen) to make helium and a neutron. Deuterium is plentifully available in ordinary water. Tritium can be produced by combining the fusion neutron with the abundant light metal lithium.

What is Fusion? Fusion is the process which powers the sun and the stars. It is energy that makes all life on earth possible. It is called 'fusion' because the energy is produced by fusing together light atoms, such as hydrogen, at the extremely high pressures and temperatures which exist at the centre of the sun (15 million ºC).

Nuclear fusion Nuclear fusion in stars and supernovae is the primary process by which new natural elements are created. It is this reaction that is harnessed in fusion power. It takes considerable energy to force nuclei to fuse, even those of the lightest element, hydrogen.

Main sequence Stars below about 1.5 times the mass of the Sun (or 1.5 solar masses (M☉)) primarily fuse hydrogen atoms together in a series of stages to form helium, a sequence called the proton–proton chain.
