Low Energy Solar Nuclear Particle Irradiation of Lunar and Meteoritic Breccias

Abundances of the elements: Meteoritic and solar

New abundance tables have been compiled for Cl chondrites and the solar photosphere and corona, based on a critical review of the literature to mid-1988. The meteorite data are generally accurate to +5-10%. Significant discrepancies between Sun and meteorites occur only for Fe, Mn, Ge, Pb, and W; other well-determined elements agree to &90/o on the average. There is no evidence for group fracti...

Chemical individuality of lunar, meteoritic, and terrestrial silicate rocks.

Energy Modeling and Simulation including particle technologies within Single and Double Pass Solar Air Heaters

In order to obtain the best performance of the solar air heaters, it is necessary to find optimum performance conditions. The aim of this research paper is to achieve optimum conditions, by comparing single and double pass solar air heaters. Also, a brief review study of various related research works of all scenarios for a single and double pass and packed bed (including particle technologies)...

Nuclear Processes at Solar Energy

LUNA, Laboratory for Underground Nuclear Astrophysics at Gran Sasso, is measuring fusion cross sections down to the energy of the nucleosynthesis inside stars. Outstanding results obtained up to now are the cross-section measurements within the Gamow peak of the Sun of He(He, 2p)He and the D(p, γ)He. The former plays a big role in the proton-proton chain, largely affecting the calculated solar ...

Solar Nuclear Energy Generation and the Chlorine Solar Neutrino Experiment

The study of solar neutrinos may provide important insights into the physics of the central region of the Sun. Four solar neutrino experiments have confirmed the solar neutrino problem but do not clearly indicate whether solar physics, nuclear physics, or neutrino physics have to be improved to solve it. Nonlinear relations among the different neutrino fluxes are imposed by two coupled systems ...
