Scientific paper

Recent discoveries concerning the composition of some primitive meteorites suggest that a nearby supernova exploded just before the solar system formed. This may have stimulated the collapse of the cloud fragments that eventually condensed into the sun and planets. Analysis of a meteorite which fell near the Mexican Village of Allende is discussed. Among the results of the analysis were the discovery of an excess of magnesium-26 which was determined to have been originally incorporated into the mineral as aluminum-26, and an excess of silver-107 resulting from the decay of palladium-107. Such isotopes could have encountered the nebula in the form of supernova grains. An expanding supernova colliding with the contracting solar nebula would result in displacement of the two colliding bodies and overlapping of their grains. This overlapping could cause clumping and eventually meteoric inclusions which would show isotopic abundance enhancement. Calculations showing that a shock wave can have such an effect along with the isotopic anomalies found in the Allende meteorite are cited as supporting the supernova explosion theory.
