Accurate abundance patterns of solar twins and analogs: Does the anomalous solar chemical composition come from planet formation?

Ramirez, I; Melendez, Jorge; Asplund, Martin


We derive the abundance of 19 elements in a sample of 64 stars with fundamental parameters very similar to solar, which minimizes the impact of systematic errors in our spectroscopic 1D-LTE differential analysis, using high-resolution (R ≃ 60000), high
