A Test of Solar-System Abundance Smoothness

Abstract

Carbonaceous chondrite (C1) elemental abundances are thought to represent the average solar system ("cosmic") composition (see e.g. Anders and Ebihara, 1982) based on the agreement between C1 and photospheric abundances and on the smoothness of heavy element abundances of odd mass nuclei when plotted as a function of mass number (A). The latter argument presently determines the accuracy of the identification.
