Looking for the complete fusion process inside our Sun.

  1. Apr 29, 2015 #1
    Hello. I want to know the full in-detail process which happends inside our Sun's thermo-nuclear core.
    As far as I know the steps in the H - He fusion process are:
    1) H+H -> He2
    2) He2 can rarely decay (Beta plus) into Deterium and a positron
    3) If so Deterium + H -> He3
    4) He3 + He3 -> He4 + 2H.
    Is this the full and detailed fusion map inside a star between 0.5 and 1.4 solar masses?
    Also a paper or article on this would greatly be appreciated.

    The Wikipedia articles are pretty good. The dominant fusion process in the sun in the Proton-Proton chain, described in Wikipedia at this link. It is somewhat more complicated than you described, since there are multiple possibilities for the D and He3 to fuse. The CNO cycle, described at this link is responsible for a small amount of the fusion energy in the sun, but becomes more important at higher masses. At 1.4 solar masses, for example, the CNO process dominates.

    You can check out this article:


    and the references included in it.

    The proton-proton chain of reactions is a little more complicated than you describe.
