Abstract:
We want to study the effects of the formation of planets and planetary
systems on the atmospheric Li abundance of planet host stars.
In this work we present new determinations of lithium abundances for
326 main sequence stars with and without planets in the Teff range
5600-5900K. The 277 stars come from the HARPS sample, the remaining
targets were observed with a variety of high-resolution spectrographs.
Description:
Li abundances for stars without detected planets from HARPS GTO
samples. Parameters from Sousa et al. (2008, Cat. J/A+A/487/373,
2011, Cat. J/A+A/526/A99, J/A+A/533/A141)
