Supernovae would be more common
On Earth carbon is not synthesized, we have what we have.In the Sun carbon is not synthesized.In red giant stars carbon is synthesized by nuclear fusion of 3 helium nuclei to produce 1 carbou nucleus. However this carbon will remain inside the star.
The very smallest "stars" in the galaxy are brown dwarfs. These are starlike objects that have failed to produce sustained nuclear fusion.
Same as all elements - in stars by nuclear fusion.
One example of a nuclear reaction involving beryllium is the reaction of beryllium-9 with an alpha particle (helium-4 nucleus) to produce carbon-12 and a neutron. This reaction is important in stellar nucleosynthesis and occurs in high-energy environments such as inside stars.
Stars are mostly hydrogen, the simplest element in the universe - also, the most common element in the universe. All the elements heavier than hydrogen were formed by nuclear fusion, where the atoms fuse together at very high temperatures and pressures. So carbon, oxygen, iron and everything else is like the "ash" from the nuclear "fire" in stars that once burned in other skies and then were destroyed in nova and supernova explosions.
If hydrogen had the lowest mass per nuclear particle, stars would be much less massive since they are primarily made up of hydrogen. This would result in shorter and less energetic lifespans for stars, leading to different evolutionary paths and outcomes in the universe. Additionally, the fusion processes within stars would be different, impacting the production of elements and the overall chemical composition of the universe.
It takes three helium atoms to create one carbon atom through nuclear fusion in stars.
Gamma rays can be produced by nuclear reactions, such as radioactive decay, nuclear fission, and nuclear fusion. They are also generated by high-energy processes in stars, supernovae, and other celestial bodies. Additionally, gamma rays can be created in high-energy particle interactions, such as those that occur in particle accelerators.
Carbon is formed in stars through nuclear fusion processes during the later stages of stellar evolution. During these processes, helium nuclei are fused together to form carbon atoms. This occurs in stars with sufficient mass and temperature to initiate these nuclear reactions.
Stars primarily use hydrogen, helium, and carbon as fuels for nuclear fusion. In the early stages of a star's life, hydrogen is fused into helium through the process of nuclear fusion in the core. As stars evolve, they can fuse helium into carbon and other heavier elements in later stages, depending on their mass and life cycle.
They are called Core Burning Stars the smallest one is OGLE-TR-122b.
In the cores of stars, nuclear reactions convert helium to heavier elements like carbon, oxygen, and nitrogen through processes like fusion. This conversion of helium to heavier elements releases energy and is essential for the life cycle of stars.
