What are the products of helium burning in a star?
Triple-alpha process Stellar nucleosynthesis Helium flash Carbon-burning process Red giant Stellar evolution Supernova nucleosynthesis Proton–proton chain reaction Dredge-up Oxygen-burning process
The triple-alpha process is a set of nuclear fusion reactions by which three 
<b>helium</b>-4 nuclei ... Both <b>products</b> are highly unstable and decay almost instantly 
back into ... When a <b>star</b> runs out of hydrogen to fuse in its core, it begins to 
contract and heat up. ... Oxygen and carbon make up the main &quot;ash&quot; of <b>helium</b>-4 
<b>burning</b>. Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by 
nuclear ... This final <b>burning</b> in massive <b>stars</b>, called explosive nucleosynthesis or 
... result, there is little mixing of fresh hydrogen into the core or fusion <b>products</b> 
outward. ... <b>Helium</b> fusion first begins when a <b>star</b> leaves the red giant branch 
after&nbsp;... A <b>helium</b> flash is a very brief thermal runaway nuclear fusion of large quantities of 
<b>helium</b> into ... However, since degeneracy pressure (which is purely a function of 
density) is dominating thermal pressure (proportional to the <b>product</b> of density ... 
A <b>star</b> with mass greater than about 2.25 M ☉ starts to <b>burn helium</b> without its&nbsp;... The carbon-<b>burning</b> process or carbon fusion is a set of nuclear fusion ... In <b>stars</b> 
between 9 and 11 solar masses, the oxygen (O-16) already produced by <b>helium</b> 
fusion in the previous stage of stellar evolution&nbsp;... A red giant is a luminous giant <b>star</b> of low or intermediate mass (roughly 0.3–8 
solar masses ( M ... asymptotic-giant-branch (AGB) <b>stars</b> with a <b>helium burning</b> 
shell outside a degenerate carbon–oxygen core, and a hydrogen-burning shell 
just&nbsp;... Such <b>stars</b> will not become red giants as the whole <b>star</b> is a convection zone and 
it will not develop a degenerate <b>helium</b> core with a shell <b>burning</b> hydrogen. Supernova nucleosynthesis is the nucleosynthesis of chemical elements in 
supernova explosions. In sufficiently massive <b>stars</b>, the nucleosynthesis by fusion 
of lighter elements into heavier ones occurs during sequential hydrostatic 
burning processes called <b>helium burning</b>, carbon burning, oxygen burning, ... 
these fuels synthesize overwhelmingly the alpha-nucleus (A = 2Z) <b>products</b>. The proton–proton chain reaction is one of two known sets of nuclear fusion 
reactions by which <b>stars</b> convert hydrogen to <b>helium</b>. It dominates in <b>stars</b> with 
masses less than or equal to that of the Sun, ... The <b>product</b> of one reaction is the 
starting material of the next reaction. There are two such ... See also: Lithium 
<b>burning</b>&nbsp;... The second dredge-up occurs in <b>stars</b> with 4–8 solar masses. When <b>helium</b> 
fusion comes to an end at the core, convection mixes the <b>products</b> of the CNO 
cycle. The oxygen-<b>burning</b> process is a set of nuclear fusion reactions that take place in 
massive <b>stars</b> ... During the oxygen-<b>burning</b> process, proceeding outward, there 
is an oxygen-<b>burning</b> shell, followed by a neon shell, a carbon shell, a <b>helium</b> 
shell ... The <b>products</b> of explosive oxygen <b>burning</b> are similar to those in 
hydrostatic&nbsp;...
