Solar System chemical abundances corrected for systematics
Guillermo Gonzalez
TL;DR
This paper investigates the systematic differences in chemical abundances between meteorites and the solar photosphere, using observed trends to correct for fractionation effects and derive primordial Solar System abundances.
Contribution
It introduces a method to correct for systematic fractionation effects in solar and meteoritic abundances, providing a new set of primordial Solar System elemental abundances.
Findings
Identified a significant trend with condensation temperature in abundance differences.
Developed a correction method for fractionation effects.
Derived a revised set of primordial Solar System abundances.
Abstract
The relative chemical abundances between CI meteorites and the solar photosphere exhibit a significant trend with condensation temperature. A trend with condensation temperature is also seen when the solar photospheric abundances are compared to those of nearby solar twins. We use both these trends to determine the alteration of the elemental abundances of the meteorties and the photosphere by fractionation and calculate a new set of primordial Solar System abundances.
