Lithium depletion in solar-like stars: No planet connection

Baumann, P; Ramirez, I; Melendez, Jorge; Asplund, Martin; Lind, K


We have determined precise stellar parameters and lithium abundances in a sample of 117 stars with basic properties very similar to the Sun. This sample selection reduces biasing effects and systematic errors in the analysis. We estimate the ages of our sample stars mainly from isochrone fitting but also from measurements of rotation period and X-ray luminosity and test the connection between lithium abundance, age, and stellar parameters.We find strong evidence for increasing lithium depletion...[Show more]
