Stylish other words, in that location is too more than helium in the universe to atomic number 4 explained by astral fusion — and the distribution too can't be explained with stellar nucleosynthesis.

These Numbers are from clayton, principles of astral evolution and nucleosynthesis, 1968, so ar slightly out of date.
Deuterium, a democratic isotope of atomic number 1, was also authoritative as a reactant in many of the reactions mandatory to form helium.
The story of the origin of the elements is closely tied to the processes of astral evolution, which describes how stars modification with time every bit a result of nuclear fusion.

Where is helium released in the nucleosynthesis process?
The helium nucleus is released at the top-left step. Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process that generates energy in the cores of main-sequence stars. It is also called "hydrogen burning", which should not be confused with the chemical combustion of hydrogen in an oxidizing atmosphere.
When did stellar nucleosynthesis occur in the Big Bang?
Stellar nucleosynthesis has occurred since the original creation of hydrogen, helium and lithium during the Big Bang. As a predictive theory, it yields accurate estimates of the observed abundances of the elements.
Which is the dominant fusion mechanism in smaller stars?
The proton–proton chain reaction starts at temperatures about 4 × 106 K, making it the dominant fusion mechanism in smaller stars. A self-maintaining CNO chain requires a higher temperature of approximately 16 × 106 K, but thereafter it increases more rapidly in efficiency as the temperature rises, than does the proton–proton reaction.
How are chemical elements created in stellar nucleosynthesis?
Process by which the natural abundances of the chemical elements within stars change due to nuclear fusion reactions. Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars.
