Evidence from the geochemical record of the evolutionary history of life on Earth suggests that life originated in a hot aqueous environment dissipating UV light and evolved later to dissipate visible light. This evidence places constraints on models of solar origin and evolution. The standard solar model seems less compatible with the data than does the pulsar centered solar model.展开更多
Within the target range from 0 to 0.1217 times the solar radius, the probability of 7Be existing as an ion with one or two bound electrons is calculated, which is turned out to be about 4.69 %, and about 95.31 % 7Be n...Within the target range from 0 to 0.1217 times the solar radius, the probability of 7Be existing as an ion with one or two bound electrons is calculated, which is turned out to be about 4.69 %, and about 95.31 % 7Be nucleus is completely ionized. After considering the influence of that portion of incompletely ionized 7Be, the renewly calculative result shows that the solar neutrino flux of 7Be will decrease from 45 000 m-2s-1 to 43 000 m-2s-1, and the predicted value of the 8B solar neutrino flux will increase from 515 m-2s-1 to 535 m-2s-1.展开更多

Tritium chain of the hydrogen cycle in the Sun including reactions of 3He(e-,νe)3H(p,γ)4 is considered. At the distance of 1 a.u., the flux of tritium neutrinos is equal to 8.1 × 104 cm-2·s-1. It is an order of magnitude higher than the flux of the (hep)-neutrinos. Radial distribution of 3H-neutrinos yield inside the Sun and their energy spectrum which has a form of line at the energy of (2.5 - 3.0) keV are calculated. The flux of thermal tritium neutrinos is accompanied by a very weak flux of antineutrinos (~103 cm-2·year-1) with energy lower than 18.6 keV. These antineutrinos are produced during Urca processes 3He3H. The flux of the neutrinos of maximum possible energy (line 19.8 MeV) produced due to the (heep)-reaction (related to the (hep)-process) is estimated.展开更多
