Lithium abundance as a function of effective temperature. Top: catalogs provided by Ramírez et al. (2012a) (in blue) and Delgado Mena et al. (2014) in green, and we retain only the targets for which a definitive measure of A(Li/H) was possible (discarding targets with only upper limits, and stars in a binary system). The stars known to harbor a planet are shown by colored spots, and those without any detected companion are represented by crosses. The two systems presented in this paper are highlighted in red and labeled. Bottom: same data sets, but showing only stars with 5500 ≤ Teff ≤ 5900.
