The relative abundances of the elements in the solar system (at approximately the time of its formation) have been compiled by E. Anders and N. Grevesse, based in most cases on laboratory measurements of the oldest meteoritic material and in some cases from the strengths of absorption lines ...
stellar models and the observed abundances of 51 AGB samples, we find that the abundance distribution of heavy elements belonging to the main-component of slow neutron capture process (SMH elements) of any AGB star is similar to that of the scaled s-process main component of the solar system...

The idea that the elements are made of the primary matter or prote hyle dates back to the Greek philosopher Aristotle. Robert Boyle, who lived in 17th century England, was of the same opinion. He said: "It seems not absurd to conceive that at the first production of mixed bodies, the ...
