Origin of elements in the Solar system / Происхождение элементов в Солнечной системе

The solar system is chemically and isotopically heterogeneous. The earth contains only 0.0003% of the mass of the solar system, but the abundance pattern of non-radiogenic isotopes for each terrestrial element has been defined as “normal”.
The outer planets consist mostly of light elements like H, He and C. The inner planets are rich in heavy elements like Fe and S. Isotopic irregularities are closely linked with these chemical differences in planets, as well as in the primary minerals of chondritic meteorites.
Chondrites are heterogeneous, agglomerate rocks from the asteroid belt that separates the two types of planets. They contain troilite (FeS) inclusions with isotopically “normal” Xe, like that found in the inner planets. Chondrites also contain diamond inclusions (C) with abundant He and “strange” Xe enriched in isotopes from the r- and p-processes. The Galileo probe found similar r-products in the Xe isotopes of Jupiter, a planet rich in He and C. The sun is a mixture of the chemically and isotopically distinct components found in its planetary system. Inter-linked chemical and isotopic irregularities, short-lived radioactivities and other post-1957 observations are used here to evaluate the two most conflicting opinions on the origin of elements in the solar system.<...>
