WebbThe supernova (SN) neutrino flux consists of two main components: a very short (< 10 msec) pulse of νe produced in the process of neutronization of the SN matter through the reaction e + p → e + n, which is followed by a longer (< 10 sec) pulse of thermally produced νe , νµ , ντ , and their antiparticles. A deuteron can also be produced by the rare pep (proton–electron–proton) reaction (electron capture): 1H + e + 1H → 1D + ν e In the Sun, the frequency ratio of the pep reaction versus the p–p reaction is 1:400. However, the neutrinos released by the pep reaction are far more energetic: while neutrinos produced in the … Visa mer The proton–proton chain, also commonly referred to as the p–p chain, is one of two known sets of nuclear fusion reactions by which stars convert hydrogen to helium. It dominates in stars with masses less than or equal to that of the Visa mer The first step in all the branches is the fusion of two protons into a deuteron. As the protons fuse, one of them undergoes beta plus decay, … Visa mer • Media related to Proton-proton chain reaction at Wikimedia Commons Visa mer The theory that proton–proton reactions are the basic principle by which the Sun and other stars burn was advocated by Arthur Eddington in the 1920s. At the time, the temperature of the Sun was considered to be too low to overcome the Coulomb barrier. … Visa mer • CNO cycle • Triple-alpha process Visa mer
