Early chemical history of the solar system
The extreme antiquity and lack of evidence for significant chemical processing of the chondritic meteorites since they were formed suggest the possibility that their chemistry and mineralogy …
Formation and evolution of the Solar System
The first step toward a theory of Solar System formation and evolution was the general acceptance of heliocentrism, which placed the Sun at the …
The Astrophysics Spectator: Table-Elemental Abundances in the Solar System
The observed elemental abundances in the Solar System are given in the table at the bottom of this page as the number of atoms of the listed element divided by the number of the hydrogen …
