Lithium depletion in solar analogs: age and mass effects.

RATHSAM A., MELENDEZ J. and CARVALHO SILVA G.

Abstract (from CDS):

The main goal of this work is to evaluate the correlation between Li abundance, age, and mass. Using high-quality ESO/HARPS data (R ≃ 115 000; 270 ≤ SNR ≤ 1000), we measured Li abundances via spectral synthesis of the 6707.8 Å 7Li line in 74 solar twins and analogs. Our joint analysis of 151 Sun-like stars (72 from our sample plus 79 solar twins from a previous study) confirms the strong Li abundance-age correlation reported by other works. Mass and convective envelope size also seem to be connected with Li abundance but with lower significance. We have found a link between the presence of planets and low Li abundances in a sample of 192 stars with a high significance. Our results agree qualitatively with non-standard models, and indicate that several extra transport mechanisms must be taken into account to explain the behaviour of Li abundance for stars with different masses and ages.
