Scientific paper

We analyze published elemental abundances derived from high-resolution spectroscopy from radial velocity planet searches. We find that the sun has anomalous abundances compared to 130 nearby dwarfs. We use a uniform sample of low mass main sequence stars to reflect differences in initial composition rather than self-enrichment. We examine individual [element/Fe] ratios as a function of [Fe/H] for 13 elements. Scenarios for enrichment of outliers are discussed.
