helium stars
Most stars that are around today are made of old material from dead stars. Those old stars produced oxygen as a product once they started fusing helium and heavier elements. Some old stars are currently producing oxygen through nuclear fusion.
Nuclear fusion. Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.Nuclear fusion.

Most stars (the so-called "main sequence" stars) convert hydrogen-1 into helium-4.
Stars fuse hydrogen into helium during the main sequence. After the main sequence, helium, oxygen, silicon and carbon are fused.
Helium
Some helium was produced during the Big Bang; the remainder was produced in stars, through nuclear fusion.
It is produced from hydrogen, by nuclear fusion.
Yes, stars fuse Hydrogen atoms to make Helium in a natural process.
If you refer to the fusion in stars, 4 atoms of hydrogen-1 combine to form one atom of helium-4.
helium atoms
helium atoms
They have enough energy produced to fuse four hydrogen atoms into a helium atom.
In the interior of certain massive stars.
All stars contain hydrogen and helium.
No. Helium nuclei are a common product of nuclear fission, as takes place in nuclear explosions and reactors. These nuclei then pick up electrons from other atoms and become whole helium atoms.
The light elements include Hydrogen, Helium, and Lithium. Some lists might include more. The light elements were initially formed in the big bang and current universal levels of hydrogen and helium agree very well with the levels produced in the big bang. Much less lithium was produced in the big bang, with most being produced later in stars. Elements past lithium were produced only later in stars.
Some stars do not develop degenerate helium cores.
